I don't want 你 people knowing what I look like! Maybe a choice few, but the Internet is so untrustworthy nowadays that I wouldn't trust it enough; AT ALL.
I'm not really into it because I'm one of those people who doesn't even want a 脸谱 或者 myspace page because I'm kind of private, and I don't want everyone who's met me since I was on a tricycle to be updated on my life. That's why I like fanpop, because 你 make awesome friends, even if 你 have no idea what they look like, lol. I have nothing against people who are the opposite...most of my close 老友记 would be into video chat :D
