hmm i can see what ur saying, but i think looks is more valid [if it's their real picture]. rating someone's personality isn't really a thing. if u think about it, all of us on GaG only know as much about each other as we wish to tell. Our personalities here are mainly formed by what we say. Some user could come on and talk shit about who they are... and how would u know? U also get people asking us what we think their personalities would be like based on their looks. i seriously don't understand the thought process behind that.
The internet isn't a very valid place of judging each other's personalities. People may get along well regularly and have common interests but anyone can be whoever they want behind a computer screen to maintain whichever sort of personality they wished they had.
Well, this is a good question. However on the internet it's difficult to say how a person's personality is because one can easily lie and fake themselves, don't you think? but your question is good no doubt.
