Wired Magazine is just out with this article about how the CIA is “investing” in online monitoring: 

    Exclusive: U.S. Spies Buy Stake in Firm That Monitors Blogs, Tweets
    * By Noah Shachtman
    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.) Customers get customized, real-time feeds of what’s being said on these sites, based on a series of keywords.
    Then Visible “scores” each post, labeling it as positive or negative, mixed or neutral. It examines how influential a conversation or an author is. (“Trying to determine who really matters,” as Cahill puts it.) Finally, Visible gives users a chance to tag posts, forward them to colleagues and allow them to response through a web interface.
    Visible chief executive officer Dan Vetras says the CIA is now an “end customer,” thanks to the In-Q-Tel investment. And more government clients are now on the horizon. “We just got awarded another one in the last few days,” Vetras adds.

Why has this development been made public? Could it be to instill fear and thereby chill public debate? You decide. I only know this: fear is the only means available to make 300 million people do things they know are wrong and don’t want to do.
