Just my observations:
I joined FB around eight years ago, a friend I grew up with in SoCal moved to Portland and convinced me to join so we could "keep in touch".
He was always a bit eccentric so I was suspicious but gave it a try.
On one of my visits up there I met my (now) wife... we chatted a bit over FB but eventually moved on to email and phone calls and weekend visits.
But I digress...

Back when I joined the membership was about two thirds to three quarters teenagers and over half the posts were about Harry Potter and Twilight (my estimates.
Fast forward to today and two thirds to three quarters of the members are adults and most of the posts are family/vacation/food/political/religious.

I don't get the hate for FB... no one is holding a gun to your head to join.
