Mike writes "A draft US Army intelligence report has identified the popular micro-blogging service Twitter as a potential terrorist tool. A chapter titled 'Potential for Terrorist Use of Twitter' notes that Twitter members reported the July Los Angeles earthquake faster than news outlets and activists at the Republican National Convention in Minneapolis used it to provide information on police movements. 'Twitter is already used by some members to post and/or support extremist ideologies and perspectives,' the report said. The report goes on to say, 'Terrorists could theoretically use Twitter social networking in the US as an operation tool.' Just wait until the Army finds out about chat rooms and email!"
