People tend to prefer their own race online in terms of the volume of messages.

You take a picture of yourself in some exceptional situation - skydiving or whatever. People always post those photos because it works - you're saying something about yourself that begs a conversation and that's what the users are there for.

Kind of paradoxically, men are very open minded or very even handed with their votes of women.

Text is, in some ways, on the way out, unfortunately. There are dating sites now that are just pictures.

We noticed recently that people didn't like it when Facebook "experimented" with their news feed. Even the FTC is getting involved. But guess what, everybody: if you use the Internet, you're the subject of hundreds of experiments at any given time, on every site. That's how websites work.

Women are much more discriminating. I think both types of people are equally interested in having an attractive partner. But women essentially give the thumbs up to only half as many guys as guys giving the thumbs up to women.

Because the way love works in general, you don't need everybody to like you somewhat - you need one person to like you a lot.
