I was doing a homework assignment (involving researching a news article about the 4th amendment, so of course I chose to search for the NSA) and came across this website hosted by The Guardian. It lists all the key events and people involved with all the NSA media currently going on, helps you to understand or "decode" what was written in the documents the Snowden leaked, and acts as a form of NSA main hub. It also has a clock that tells you exactly how much data the NSA has collected in the time that you have been on the website. It's certainly something worth checking out in my opinion.

In the 4 minutes that it took me to create this post, for example, it says that the NSA has selected 196.3 Terabytes of data for review.
