This is huge.  Google is finally able to publish information about the number and scope of the FISA (secret intelligence court) subpoenas received.  The takeaway:  it's massively fewer subpoenas and accounts involved than many people suspected.

There are caveats.  Google is required to delay reporting by six months and required to only report information in bands of 1,000.  But it's massively better than nothing.  

The world, but especially US citizens, have a right to know what kind of surveillance their government is authorizing.  It has been cool to see companies like Google push for this kind of openness.  Reform is a long time coming and this is only the beginning.  Baby steps.
