There is really nothing wrong with meeting girls on the internet. This isn't ten years ago, this is now. I met my girlfriend on hotornot and we've been dating for over a year now(and she's good looking too).
For guys, it is mandatory that a picture be posted. Make it a good one, too.
Women, although they like to say they care about personality etc., are the same as guys: they go for looks first.
If your picture isn't up, they will not read anything, and just assume that you're either ugly, lacking confidence, or not using the dating service anymore.
The moral of the story is: if you are using internet dating, you have to post a picture.
