Facebook lost me a while back when the Android app first came out. Logging into the site and finding contacts that had no account in my facebook "phonebook" felt like a breach of trust. I figured they'd act in good faith and enrich Android contacts with facebook data. I did NOT think they'd yank my contacts the other way, doing who-knows-what with it. Shame on me for not reading the app permissions with more scrutiny.

Leaving facebook removed a distraction I did not realize I was weary of. At risk of sounding dramatic, it felt like I got a few minutes a day of my life back.
