Nerds Giving Back--Patrick Rothfuss' World Builders charity

I caught an interview with writer Patrick Rothfuss on NerdNighters recently and he was talking about his charity WorldBuilders. I went to the sight and found his blog and a store with all sorts of goodies for sale, from autographed copies of his books (what fantasy lover wouldn't like an autographed copy of The Name of the Wind?) Rothfuss supports Heifer International, one of the best organizations out there for empowering individuals and communities.
