We’re still following what’s happening with FISA, and we saw some interesting trends today. Look at the difference in coverage of FISA on different mediums.

Here’s at look at the number of posts about FISA on Twitter over the last two weeks.

You can see that there was more chatter about FISA on Twitter yesterday than at any point over the last two weeks. That’s a different story than what you see when looking at coverage from mainstream news sources and blogs.

Here are the stories about FISA picked up by Google News over the last two weeks:
