No, it really isn't. If you are using Facebook or Twitter with anything other than an expectation that the information is public (in the sense that US law enforcement can look in), then frankly you deserve everything you get. These are networks that exist for the sole purpose of sharing data. They are optimised for sharing, not for privacy, and this is how it should be. If you don't like it, don't put sensitive information on social networks.<p>The really concerning news out of all of this is that services like Gmail, Google Docs, Dropbox and other services that are more aimed at synchronising data than with sharing it are being targeted by law enforcement. In these cases we have a much more reasonable expectation of a certain level of freedom from governmental scrutiny.<p>Even more concerning is the invasion into the privacy of point-to-point communications, Skype, various chat programs etc. Obviously there are some grey areas in this distinction - where does Facebook chat fall for example. My personal feeling is to go back and look at the main purpose of the site in question - when I am on Facebook I feel like things are public. When I'm exchanging emails with a friend, it feels much more private. An email to a group of friends on the other hand does not feel anywhere near as private as a one on one exchange. Meh - these kinds of distinctions are precisely why we have human beings known as "judges" in the legal system.<p>At any rate I for one would not feel any more secure and private when using a Diaspora-style architecture than when I'm using Facebook. Why? because the whole point of social networks is to share, not to hide. If you really want to hide stuff, use encrypted point to point communications methods, preferably buried in a near-constant traffic stream that ideally bounces off servers in several different countries. You'll note that this level of security is many many orders of magnitude more difficult, but that's normal - sharing and security are diametrically opposed.
