U.S. SPIES BUY STAKE IN FIRM THAT MONITORS BLOGS, TWEETS

America’s spy agencies want to read your blog posts, keep track of your Twitter updates — even check out your book reviews on Amazon.

In-Q-Tel, the investment arm of the CIA and the wider intelligence community, is putting cash into Visible Technologies, a software firm that specializes in monitoring social media. It’s part of a larger movement within the spy services to get better at using ”open source intelligence” — information that’s publicly available, but often hidden in the flood of TV shows, newspaper articles, blog posts, online videos and radio reports generated every day.

Visible crawls over half a million web 2.0 sites a day, scraping more than a million posts and conversations taking place on blogs, online forums, Flickr, YouTube, Twitter and Amazon. (It doesn’t touch closed social networks, like Facebook, at the moment.)

As time goes on, "Big Brother" seems to find more and more technological means of spying on us.
