While true, is this just the first example of a social site that has gotten big enough to attract your parents? Or is this the first site your parents will, for lack of a better term, abandon just like others did with myspace?
I think it's the case that Facebook has just gotten that big. Also, it doesn't have terrible custom backgrounds like MySpace. To the extent that they can avoid that, I think they'll be ok. There's probably a few other things they should focus on too...
Yeah, I don't know that it's really anything to do with Facebook per se, but rather the fact that it's 2012 and people's parents are now signing up for social media sites.
