I'm glad this article puts a spotlight on this, but my gosh! Could it be more vague? What are the subjects of the NSLs? Was this article written too soon after the documents' release to give a summary of the juicy bits? To me this basically reads like "a company released some government documents". Is this typical of TechCrunch?
