If they manage to get the NSA off the backbones and repeal PATRIOT so the feds can't review my entire digital life in realtime with no warrant, I will move back to the USA.
(But of course not NYC where you are subject to illegal search just riding the subway.)
If you're still talking to people in USA, especially through Skype, your conversations are probably already monitored [1]. I think NSA already has a (secret, illegal) mandate to monitor all American communications with any foreigners.
It sucks because I don't have any good ways of securely communicating with voice and/or video to people on mobile in the US. PGP, OTR, SSL, etc work well, but there aren't any good PGP or OTR clients for iPhone AFAIK.
I mostly just censor myself until I can speak to people in person, or communicate only unimportant things.

I ain't holdin' my breath. :(
