Facebook Does NOT make you "kindly".

While inspiring people to appear "kindly" may have been one of Mark Zuckerburg's goals in creating Facebook, the site is certainly not doing so.  Social networking sites cause people to try and make their sites appear 'cool', if anything.  Users want to be accepted.  It's more about seeing how many friends one can get than actually caring about what those 'friends' think about you.  If a student, or whoever the account holder may be, is trying to impress, then their aim is most likely not to appear like a good person.  That member would put on their website what the people they want to be friends with would want to see.

Facebook is not a world-changing, peace-inspiring, let's-save-the-world-attitude inducing website.  It is what it is; a place for social networking.
