Well you have to get voted first and to be fair, this site isn't really about being beautiful. For example, if you area decent looking person who is in a relatively ok shape then you are in if you take a nice pic and have a decent facial expression.
Also I agree that it is vain but goddamn if you are looking for a hook up with decent looking people then why not? I guarantee that if 99 percent of the people go on a diet and take care of themselves then they can get in too. Most people do not live up to their potential of how good they can look.
I have seen below average chicks go on a diet, change style and clean up and they look hot. Same applies with guys, some dude with a neckbeard and a belly can stop eating the shitty fast food, go on a good solid diet, works out, dresses well and cleans up, he too can look like a stud.
Reality is, most people don't take care of themselves and every time I walk past a fast food, its FULL of people and there is tons of fast foods around or people just drink themselves a new pot belly...
