Yeah, I'm finally there too.
But I'm mostly not into it at all.
The only redeeming quality I see to it is that I have been contacted by a few old friends (i.e. high school, which was nice).
Other than that, it's just not my kind of thing.
But I think it's very cool for kids. My son keeps in touch with friends in VA that he grew up with, and kids he sees everyday in school. Not that I'm snooping. But if he sneaks onto my computer, and forgets to clear his history, he's fair game in my book.
At 15, he is generally way cuter there than he is at home!
But I am a privacy fanatic, so I never spend more than minute or so. All seems good. I almost wish I wasn't his Mother, so I could enjoy him more!
Be careful who you add as friends. Or it will be just another re-run of here.
