citydate is pretty useless. it's especially heavy on the useless images and graphics. they're obviously trying to make their site look "prettier" and more "professional" than they really are. in reality, any professional web designed will tell you it's run by amateurs. it's funny how they advertise "real people" use their site, yet most of profiles of women are fake profiles w/ photos from adult porn sites and webcam sites. they're sneaky like that.
i critiqued facemeet on another post. facemeet is even worse than citydate. not even worth going into here.
mathdoctor is advertisement city. they like to change the look of their site about every month in hopes of hiding the fact their site is useless on the inside. weak search tools. horrible site navigation. advertisements on every page. fake profiles. takes forever to get a photo approved. these guys are the worst of the worst.
houstonconnect needs to clean up their site. it's too disorganized with links everywhere, useless images, and tedious sign up process. i hate sites that require you fill out your profile when you sign up. search is ok, but can see less than 10 profiles at a time. be prepared to scroll a lot.
chicagomixer, although not great, is prb the best out of the 5 listed here. good search capabilities. very fast page loads and easy to get around and find the things you need quickly. photos get approved within an hour or two. and they make it clear they're a dating site. they're also not a totally free service, so i guess that keeps out the riff raff who aren't serious. but you can reply to emails for free. it's too bad they're only for the chicago crowd. they could probably do well on a national level like match.com or lavalife.
so in conclusion, on a 4 star scale:
citydate - * (1 star)
facemeet - * (1 star)
matchdoctor - * (1 star)
houstonconnect - ** (2 stars)
chicagomixer - *** (3 stars)
