Ask Neal about Anathem
It seems the EOS Books blog has a little something of an inside track to Mr. Stephenson, and they are going to harvest the best questions (posted or e-mailed) and he will answer them via a video post to the site. You leave your questions at the link above or e-mail them directly to eosbooks at harpercollins.com. But HURRY you only have until Tuesday May 26th to get your questions in.
