Snowden merely confirmed a widely held suspicion that the feds are recording and analyzing most modern communications. The notion that terrorists didn't already assume this and use encryption online and burner cell phones is dubious to me. If anything, Snowden may have stopped some would-be terrorists by showing them just how many ways there are for them to get caught.

There's also another layer to this: The terrorists that actually exist are not 10 feet tall and not all geniuses. If I told some of my non-technologically oriented friends how to encrypt and anonymize their communications, they couldn't do it. If I went one step further and configured their computers and explained to them how to use it, they would probably still leak information by misusing it.

Are the terrorists changing their tactics? Probably. Is it going to do them any good? Unlikely.
