There are now a number of sites dedicated to spreading the word about p2p computing. However, p2pnet.net was one of the first, and is still one of the few (perhaps the only one) zeroed in on p2p information / people / news / applications AND the people trying to shut p2p down.
p2pnet.net is always looking for contributors - application developers, writers, musicians, people with knowledge of the entertainment industry from any and all perspectives.
Its founder / editor is Jon Newton.
