I agree that Snowden did it about as well as you could possibly hope for a whistleblower exposing classified information. Manning meant well, but was naive and sloppy. Assange started out with good ideas, but seems to have gone mad with power after the Manning leaks. Still, some of the stuff that Manning and Assange leaked, did need to be exposed. It should have been handled more responsibly, but it still needed to be done.
