From Nicole Perlroth’s report in the New York Times:
Homeland Security seems to have a real affinity for Twitter. It advises its employees to follow not only Twitter itself but also Twitter search sites like Monitter, Tweetzi and Tweefind and more than 10 Twitter trend sites like TweetStats and Trendistic.
It monitors Facebook and, while it also recommends monitoring MySpace, it notes the once-popular social network has “limited search” capabilities. Homeland Security employees also monitor video sites like YouTube, Vimeo and Hulu — “situational awareness” apparently entails full episodes of “The Bachelor.”
