It seems that Army intelligence analysts fear that Twitter (a micro-blogging service), cell phones, and GPS utilities are of concern because they could be exploited by terrorists to coordinate an attack. This is on the heels of earlier concerns that virtual worlds (e.g. Second Life) and social networking services (e.g. Facebook) could be used by terrorists as well.

I do think it’s good that our analysts are creating scenarios that leverage widely available technology, but I don’t think this is any reason to be concerned about these technologies, much less to put any special measures in place to regulate them. After all, you can use a screwdriver to build a bomb or even to stab somebody. But I don’t think that’s any reason to put a 7-day waiting period on the purchase of a #2 Phillips head.
