Going to a site with more users seems obviously better to me, but at the same time, having a bland, middle of the road profile with bland, middle of the road pictures seems like a bad strategy to me.

A great piece of advice for online dating is to stand out from the crowd. So greetings like "hello" and "hi" are very common. They do less well than things that are a little bit quirky or a little bit weird, like "howdy" or "holla." The rarer your salutation, the better it does, in general.

There will be more words written on Twitter in the next two years than contained in all books ever printed.

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

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.

I know that shorter messages are better in terms of reply rate. The optimal length is something like 50 characters. Characters, not words.
