But yeah - the quest to have the most 'friends' is ridiculous. I certainly know people who I am pretty sure added me for that reason alone. Some girl who was part of a social group I got ousted from because the alpha male decided I was "gay" way back in grade 6 or something added me to Facebook, she wasn't a bad person at the time or anything, so I messaged her to say hello and ask what was up and where she had gone in life, and she totally ignored me. Don't really care, but why ad me if you have no intention of ever talking to me?
One thing I have in praise of facebook and the like is that at least they are pretty open and dynamic communities with plenty of good and bad areas... you to some extent don't get the same kind of screwed up stuff happening on tightly controlled things like Suicide Girls, where the administrators and moderators are just as petty as much of the community, if not more so.
