> You people (over 30) are not real users. Please understand this.
Baseless generalization. There's some age correlation there, no doubt, but I know people over 30 who use Facebook as enthusiastically as the most social of high-schoolers, and I know people under 30 who won't touch it. At least among the technically inclined, Facebook usage style is more a matter of personal disposition than age. It's stupid to say nobody over 30 has anything useful to say about the site.
And the over-30-year-olds I know who make minimal use of Facebook? They have plenty clue "about how Facebook actually works", thank you; due to their years of experience I find them often more clueful than the most voracious teenage user. They just choose to use the site differently, or not at all, regardless of their level of understanding.
I myself am well under 30, by the way, lest you accuse me of an age group bias.
