Specifically, DHS wants to monitor blogs looking for evidence of terrorists about to use IEDs (improvised explosive devices.) They will also examine message boards, Twitter and online games.
Um, if you were going to blow something up, would you blog about it first? While any of those online sites could be used to pass messages, they would almost certainly be encrypted, concealed with steganography, or otherwise hidden.
That DHS (Hi there!) might be monitoring blogs concerns me not. Google monitors this blog several times a day as do multiple another search engines and spiders. In fact, that’s what the Net is about. Open access to data and do with it as you will. Hey, maybe DHS should just use Google instead!
