Using Wikileaks To Figure Out What The Government 'Redacts'
The ACLU [has] set up a special page allowing people to compare multiple versions of documents with just a simple mouseover. This came out a few months ago, but I didn't get a chance to write it up until now. It's pretty enlightening to see just what makes the censor's cut, and (not surprisingly) raises significant questions about the government's temptation to simply excise stuff they don't like, rather than information that there are valid reasons to keep hidden.
