I've noticed the falling total numbers, bit locally they have most of the market, and the competition seems to be the ones falling. But whatbdo you expect when RSVP charges $15 just for a one month stamp to talk to just one person. I wonders ifntheir imvrstuts know they are going to do all.their investment money this way. Eharmony is a nightmare with people behind a firewall (and thosevawful ads). Okcupid remains but doesn't seem much. Match.com doesn't seem much. Oasis remains but doesn't seem much. And POF seems to mean Plenty of Fanny (despite how they act) has most of the people and is not that good except the tests seem a lot less a waste of time than okcupids, and seems to be effective.
Honestly, a better dating site than any of these can be done, and POF look like oasis.
