I've come to a similar realization, and reacted against G+ in much the same way. Maybe the NSA or ONI can figure out who 'revscat' really is -- and honestly, in my case it wouldn't be that difficult -- but Google already knows more about me than I feel comfortable with. The only way I would consider switching from FB to G+ was if Google completely reversed their 'real name' policy and allowed/encouraged pseudonyms.
The internet has a long, long history of anonymity. I will continue to do what I can to support this.
