"the oldest Internet resource devoted to politics and technology. Launched in 1994, the Politech mailing list has chronicled the growing intersection of law, culture, technology, and politics."
I still meet privacy professionals who haven't found Politech yet, possibly because it is not purely about privacy, but it is well worth subscribing, for Declan's even-handed reporting, and for that early "heads-up" you sometimes get from insiders (e.g. it is where I first heard about the UCLA taser incident).
