An anonymous reader writes with this excerpt from Wired: "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... Visible Technologies 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. 'That's kind of the basic step — get in and monitor,' says company senior vice president Blake Cahill. 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."Apropos: Another anonymous reader points out an article making the point that users don't even realize how much private information they're sharing over these services.
