I haven't been this excited for a comeback since the Spice Girls reunion. Here's hoping the relaunch of the OkTrends blog lasts longer than the relaunch of everybody's favorite 90s pop girl group.

The disappearance of OkTrends, the quirky but insightful blog of OkCupid, was always a mystery to me. It dominated the web while it was active, and is undoubtedly one of the greatest marketing ideas ever deployed, but for some inexplicable reason the blog fell dormant.

"From August 2010 to April 2011," says Digiday.com, "OkTrends posts averaged a staggering 32,500 Facebook likes and 4,222 tweets." With OkCupid co-founder Christian Rudder at the helm, the blog took off and introduced the site to millions of new potential users. But then, shortly after IAC purchased OkCupid in 2011, OkTrends disappeared and many felt that the purchase was to blame.

Rudder, however, firmly denies the suggestion. He cites a lack of time due to other responsibilities at OkCupid and a new book he's writing, called Dataclysm, that's due out in fall 2014. Rudder promises the book will be "a superset of all the stuff I did on OkTrends." Digiday adds that the book is described as "a witty, provocative, visually fascinating look at how 'big data' is transforming our understanding of race, politics, age, beauty, sex, humor, even history, and ushering in a new era in the study of human nature."

Ok, count me in. Sounds like an intriguing read. But what about that OkTrends blog, huh? Sometimes I prefer to digest my information digitally. Why not just hire another writer to cover while Rudder finishes his book?

"This is just going to sound very self-serving, but I just don't know if that's possible," he says. "I'm in the unique position of being a founder of the site. I just know it so incredibly well...I just don't know how you find someone out there that can do it."

A little narcissistic, maybe, but the man's probably right. It would be a disappointment for all of us if the blog came back and was only half as good as the original. Do it right, or don't do it at all.

The good news is, OkCupid is going the "do it right" route. Rudder plans to rekindle the blog in March, after he's submitted the manuscript for Dataclysm, and he promises it's going to be better than ever.

"I'm excited about starting it back up again," he teased in Digiday. "I'm definitely going to try and bring a new little twist."

Choosing the right picture for your online dating profile is an art form.

Wait a minute, you don't even have a profile picture? Ok, let's start right there: get one. Stat. You're gonna need it.

Here's what you need to know to choose one that brings all the boys (and girls) to the yard:

1. Do take candids. Candid shots that convey less effort tend to get a better response than professionally posed pictures. On average, candids receive 2x the messages that professionally posed photos do.
2. Don't pose in the bathroom. Please, just don't. No one has ever looked good with grout in the background.
3. Do share your passions. Show off your personality in pictures instead of words. Upload shots of you engaging in your favorite hobbies, pastimes, and passions. Action shots lead to 3x the amount of interest and higher quality conversations.
4. Don't do duck face; do do a kissy face. If your lips are parted, people are 5% more likely to be attracted to you. On top of that, women are 32% more likely to be chosen by someone when they pucker their lips into a kissing face instead of just keeping them sealed.
5. Do wear red. Both men and women find those who wear red to be more sexually appealing. Rawr.
6. Do put on a happy face. I don't need to tell you that people aren't looking for angry or sad dates. People are 12% less likely to click on you if your profile picture expresses a negative emotional state.
7. Don't post huge group shots. It just gets confusing. If it's not obvious which one is you, it's not a good choice for your dating profile.
8. Do go for natural light. It's the most flattering, and could make you look as much as 10 years younger.
9. Do remove your glasses. Online daters are 28% less likely to click on your profile if you're wearing glasses in the picture.
10. Ladies: do make eye contact. Making eye contact and flirting directly with the camera gets the best response from potential suitors. Think "Myspace angle."
11. Men: don't make eye contact. Men get better responses when they are staring at something off in the distance with a charismatic smile. Think "I'm too cool for direct camera contact."
12. Do smile! People are 45% more likely to select profile pictures when the subject is smiling.
13. Do find the sweet spot. 3 photos is the ideal number. Profiles with 3 pictures receive up to 85% more messages than profiles with more or fewer.

Not to brag or anything, but I think we ladies have it pretty good when it comes to the dating game. Sure, everybody has their ups and downs, but if we look at the way things are often run around here, we definitely seem to come out ahead in the online dating world.

Josh Fischer, the Director of Product Insights at SNAP Interactive, the company that owns Are You Interested, put together a collection of charts that shows exactly how women have the advantage over men on online dating sites. Each chart examines the probability that men and women respond to messages given the age of the message's sender.

The likelihood that an American woman responds to a man on AYI.com drops significantly as the age gap between them increases. The younger the man is, relative to the woman, the better shot he has. The probability of receiving a response peaks when the man is 7-8 years younger than the woman, and steadily declines from there.

The likelihood that an American man responds to a woman on AYI.com varies much more, and the response rates across all age differences are far higher. In fact, it actually dips the lowest when the man is 7-8 years younger than the woman. Merge the charts together, and they don't ever cross paths. Not even once.

Over all, AYI's charts show that, when comparing men and women responding to people their own age, women respond to men 4% of the time while men respond to women around 18% of the time. In other words, the vast majority of messages go unanswered regardless of age or gender.

It also means that the average straight man will have to send 25 messages to women his own age in order to receive one response, while the average straight woman will have to send just 5 messages. Hardly fair, if you ask me.

According to BusinessInsider.com, these conclusions can also be drawn from the data:

• A straight man's best bet is to go the Mrs. Robinson route. The 8-10% chance that a woman 10-8 years older than a man will respond to a message is double the rate of his own peers.
• The New York Jets have better odds of going to the Superbowl this year than men of a certain age have of getting a response from a woman ten years younger. Ouch.
• At worst, there's a 1 in 6 chance a man will respond to a woman's message regardless of her age. So go for it, ladies - you've clearly got nothing to lose.

Sometimes when there are seemingly endless options available to us, making a decision can be difficult. Having too many choices can work against us - the more we have to choose from, the more overwhelmed we feel and the less informed choices we make.

Such is the case with online dating. While it brings us constant opportunities to meet new people, it can also give us a "grass is greener" complex. Here's how it works: No matter how great the person is sitting across from you, you think there might be somebody else who's even better. So you don't pursue this woman you find so attractive simply because you want to keep your options open. Instead, you go back to your online search and look for more matches to contact, more dates to pursue. You've become a serial online dater.

While this might make dating more exciting, you're making a sacrifice - you're actively choosing not to pursue or cultivate a relationship. Until you decide to stop your endless search and focus on the person sitting across from you, you'll never get to the relationship part of dating.

It's pretty easy to go online and search for dates, so it's no wonder some of us use online dating to avoid any type of commitment. Especially if you're heart is broken. Maybe you feel like the people you love cheat or abandon you, so why would your date be any different? The problem is, if you don't give someone a real chance, then you'll never find out if it can be different.

If you're a serial dater, you also might be thinking that you just haven't met "the one" yet - the elusive woman or man who sweeps you off your feet, who is so much more beautiful, successful, adventurous, funny, etc. than anyone you've dated so far. It's just a matter of time, right? Not so much. The truth is, you're not giving the people you're meeting a real chance. You haven't taken the time to get to know them and see if there is a real connection. Instead, you're relying only on chemistry or infatuation or unrealistic expectations, which aren't great barometers of long-term relationship success.

And if you are constantly analyzing your dates, looking for faults? You'll never find that "perfect" person, because everyone comes with some sort of history or baggage or preconceived notions, including you. It's important to be honest with ourselves about who we are and what we bring to the table, faults, weaknesses, strengths and abilities. We are all wonderful in unique ways, and we are also human beings.

Instead of serial dating, try making a real effort with the next person you ask out. It could make all the difference.

In fact, it's so easy that I'm not sure it can be called hacking. It doesn't even have to be done intentionally - just one little oblivious click, and suddenly someone else is logged in under your username.

It works like this: when OkCupid sends you an email, any links included inside the email contain a unique identifier called a token. When you click the link, you are automatically logged into your OKCupid account without having to enter your password. The point is to make it as easy as possible to get into your account, but it also makes it worringly easy for someone else to do the same thing.

A writer at The Verge discovered the security hole after receiving a forwarded OkCupid email from a friend. After reading the funny message her friend had received from a prospective suitor, she clicked on the message to see the suitor in question.

"Suddenly," she writes, "I was in my friend's account, staring at all her read and unread messages. I could see her instant messages. I could edit her profile. Just because I had clicked on an email sent to her, OKCupid thought I was her."

Although your friends probably won't do anything unscrupulous if they land in that situation (you hope!), it might not be your friends who unexpectedly find themselves logged into your account. In another case, a woman blogged about an OKCupid user and included a link to his profile that she copied from her email. Unbeknownst to her, any reader who clicked on it would then be instantly logged in as her.

There may be a little karma involved here - because it doesn't seem very nice to publically blog about a user and include a link to their profile - but no one wants to give every stranger on the Internet access to their online dating profile. The token does expire eventually, but no one has yet determined how long it remains active.

Naturally, the OkCupid forums have exploded over this. In one discussion thread, a user writes "This totally defeats the purpose of having a password for the site. If anybody happens to be able to read my email, they are then able to see my full OkCupid account. Hello, what kind of account security is this?"

The thread has been active since 2009, so as incensed as OkCupid users may be, the site doesn't appear to be in a hurry to address the issue. Although "Login Instantly" is not a new feature, it is perhaps not the wisest choice for a social network, dating site, or other online destination that contains such personal information.

Think twice next time you're tempted to make fun of a fellow online dater by forwarding their hilarious message on to your friends. Stick to screencaps or - here's a really radical idea - just be nice and don't do it in the first place.

A picture might be worth a thousand words - but sometimes it doesn’t hurt to add in a dozen more to explain the situation. And thus, the invention of the caption. Here’s a little bit about when you should make sure your online dating photos include captions, and why.

First, your default picture should probably be self-explanatory enough that you don’t really need a caption; after all, the main event is your face. Even if you’re going for an “attention-grabbing” default picture, it shouldn’t be so out there that it causes a reaction along the lines of “What in the world is that?” You might be skydiving, but it’s obvious you’re skydiving. In general, however, the default picture should have a nice, clear shot of your face, preferably smiling, so there’s no confusion over whether you’ve used a mugshot.

However, nice as those pictures may be, they can sometimes be lacking in character. That’s when you start pulling out other, more interesting photos; photos with a story behind them. But here’s the catch: you need to either explain the story behind them (in a succinct way) or make sure the photos are really as interesting as you think they are, even without the story. The picture of you dressed as a lobster might be funny, but it’s even funnier when you explain you stumbled into being an extra for the Ice Capades last year - and it might reveal a little something extra about your personality, too.

Then there are the photos that can be called Potentially Deliberately Misleading. For example, a picture where you’re casually posed with a celebrity. In reality, you stood in a convention line for an hour to get this photo; however, you might neglect to mention this because you’re okay with the assumption that you’re just friends with famous people. Even though you’re not actively trying to deceive, it might look that way to others. Or imagine a photo where you’re being swarmed by children. Are they yours? Are they your nieces and nephews? Do you work at a day care? The lack of a caption that clarifies the situation might make it seem like you’re actively hiding something. Thus, perhaps it’s best to be crystal clear from the beginning.

Finally, there are photos that just need a little clarification. Yes, once you’ve met in person it’ll be pretty easy to identify you in a crowd, but when you’ve only got one or two photos to go by, the reader might not be able to pick you out of a group shot of bridesmaids or fraternity brothers. If you’re going to include a group shot, make sure it’s obvious which one you are.

Captions are not meant to be additional profiles, but when used correctly, they can eliminate confusion and enhance the stories told by your photos. Do your photos need explaining?
