My entire problem with Facebook has been based around invasions to my privacy. As the years went on, I realised that more and more of my privacy was being eroded. I realised that Facebook really didn't care. I realised that I was helping them to build one big database that was searchable and rampant for abuse by a rogue government agency.
My quitting of Facebook meant nothing really. They already had all of my data, and primarily, my contacts and a profile picture. The "deletion" of my account just meant they switched my account status from "active" to "deactivated" to "deleted".
I'm not naieve enough to believe that they really deleted all that info. I proved several times to the contrary previously through minor Facebook bugs.
At the end of the day, Facebook is company that over time more and more people won't trust. The demographics are already changing and ageing.
The key thing I have taken away from deleting my account t is much like yourself. I realised that I don't actually miss it. The people I was friends with on Facebook weren't my day to day friends. To be perfectly honest I don't have many.
Everyone on Facebook that I knew were exes. Ex work colleagues, ex girlfriends, ex friends. If they want to keep in touch then they can find other ways to contact me.
Maybe we can meet up and have a face-to-face, away from the prying eyes and ears of the snooping governments that we all live under in 2013.
One final thing. I will discourage my kids from having Facebook accounts. I hope I can teach them about their privacy, such that they don't want one in the first place.
