I hear ya. And you know, I've come across a few morons who insinuated to me that I am anti-social and have Aspergers' because of my resistance to using Facebook.
All privacy questions aside, I quit Facebook simply because every time I used it, the "after taste" was that I'd wasted my time and made myself stupider in the process.

Really? All my friends who use facebook at first thought it was a useful tool, and then slowly the bloat beyond the first few friends you actually give a shit about occurs.
Your feed started becoming invite spam and people who you dont even really know commenting on their breakfast or their kids or their cat doing a dumb thing.
All I can think of when I see this on other people's screens (though most of the app invite spam has been taken care of):
"Great minds discuss ideas; average minds discuss events; small minds discuss people."
