Dave Farber runs a great mailing-list called "Interesting People," where he posts little snippets of tech and policy news throughout the day — tons of links on Boing Boing originate with IP.
If that wasn't reason enough to sign on, check this out: Tim O'Reilly is offering a 30 percent discount for the upcoming OS X conference in Santa Clara for IP readers — just mention IP to the registration people and they'll knock off the discount.
(Thanks, Tim!)
