This is exactly what I was wondering the other day if it was possible, you nailed it on the head, major props. Basically nobody in high school is on match.com or other dating sites because it's not legal and kids just don't seem to do it. So this is a fantastic algorithmic way to optimize who you should be talking to. A huge factor in finding a good person to date is familiarity and their closeness to you. If they see you all the time and you send out trustworthy, non-socially awkward signals, they are likely to trust you more.
Haha very true, I was going to continue on with that comment and explain more. But then I went back and actually read the end of the article and realized it was about how creepy Facebook is and not really about finding a better date through Facebook. So I was going to either delete the comment or just leave it as is and see if anyone understood it, so it's funny in that way.
