I've browsed a couple of dating sites through the years, and from 1-10, the average woman on there is a solid 7.5 - 8.... provided there aren't many 9+ women out there and it's a dating website, I find that very strange.
Okay, so maybe these women are just more comfortable putting themselves out there than the <7s, they know they'll get the responses, and after going through several assholes (wait, that didn't come out right.. er, that's what she said) they've decided that getting trashed at a bar isn't going to land them Mr Right... or maybe most of them are bots or it is another way to find Mr Right Now... and I'm not complaining, but it's just odd. And not just beautiful, either, but women with multiple degrees that own their own businesses, etc.
It's not even close to a random sample of society, much less the single ones.
I guess like what GoChiefs is doing, it helps confidence though, because there's no way in hell I'd approach them in real life... at least if I send them a message, they can laugh and delete, instead of you know, just laughing.
