A trustworthy frind of mine says someone trustworthy says:
For those on Twitter: Set your location to Tehran and your time zone to GMT +3.30. 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 & please pass it on.
Okay, this was enough to get me to sign up for Twitter. I'm gerifsullivan there as there were already four other Geri Sullivans. My bio shows me as the Geri Sullivan of Toad Woods. Location and timezone as above; I'll reset it when it's no longer productive to have it as is.
