I met an American guy around 2005 who told me something that got me to think: He did not use any "public" email service (gmail, yahoo, hotmail, etc). When I asked him why, did he believe the government could do something to him? his answer was (heavily parphrased):
"It is not about what the government can to today with it, it is what the government will be able to do in the future"
You may believe that your dick picks are OK now and laugh at the thought of some FBI/NSA official having to comb those on a friday afternoon. But in 10/15 years time you may be in a situation where, said official will bring your dick-picks as evidence of how since so long ago you were a crazy sex maniac.
