The Guardian, which has done almost all the heavy lifting on the ongoing NSA story, has an excellent recapitulation of the story so far and what it means for us. The page is interactive and has snippets of video interviews with several people involved in or knowledgeable of the story.
Although The Guardian has been merciless in their coverage of the scandal, the recapitulation is very even handed and gives voice to both sides: those who support the NSA and its activities and those that deplore them. They also include many of the (previously published) source documents. If you’re at all interested in the NSA story but not obsessive about following it like, ahem, some people this is a great summary. On the other hand, if, like me, you’re one of those obsessive folks, you won’t want to skip it either.
