USA Today reports (Feds may mine blogs for terrorism clues) that the US Department of Homeland Security wants to use data-mining technology to search blogs and Internet message boards to find those used by terrorists to plan attacks.

“Blogging and message boards have played a substantial role in allowing communication among those who would do the United States harm,” DHS said in a recent notice.

Julian Sanchez notes on Ars Technica that the story is not new.

“The story is actually pegged to a Sources Sought Notice posted by the Department of Homeland Security back in October. Our colleagues at Wired reported on it at the time.”
