Using Twitter to crush a revolution

According to Mark Shea, Iranian security forces are using Twitter to hunt down bloggers via location/timezone searches. He makes the following recommendation for those wishing to support those in Iran who wish to see democracy come to their country:

If you use Twitter, set your location to Tehran & your time zone to GMT +3.30. Iranian security forces are hunting for bloggers using location/timezone searches. The more people at this location, the more of a logjam it creates for forces trying to shut down Iranians' access to the internet. Cut & paste & pass it on.

Hopefully this will work/help.
