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

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.

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

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

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

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.
