To be fair, there was one person on GU Talk who was always worth listening to: PolicyWatcher could pretty much fix any computer problem anywhere in the world from memory, and he was slating the ID cards proposal on technical, legal and political grounds YEARS before anybody else.
I couldn’t tell you if he was a left-winger or a right-winger; I only know that I look like a ruddy noob compared to that dude and that’s despite working in the same field as him for over a decade.
GU wasn’t without its “celebrities” either. Garrick Alder was notable for being one of the question wranglers on Q.I. He left GU Talk a few years ago though.
