If you haven't been reading Sham's Grog 'n Blog and you're a fan of OD&D, you should be. Its author, along with Philotomy, is one of the most insightful commentators on the three little brown books out there in the ether; he's inspired me more times than I can count. Of late, Sham has turned his sights on reading OD&D cover to cover and discussing his thoughts as he does so. He's currently up to Part 7 of the series and still has a long way to go!
