I regularly lurk on a homebrewing forum called homebrewtalk.com. The site is filled with useful information about refining your techniques, building your own homebrewing equipment and other and sundry assorted topics related to homebrewing. It is the single most useful resource on the Internet for homebrewing information.
Recently, the creator and maintainer of that site has branched out and started a set of forums talking about craft beer at beerforum.com. Based on how well homebrewtalk.com has done, I would expect this site to become a bastion of craft beer light shining into the darkness. If you love good beer, you should definitely check it out.
Full disclosure: Beer is awesome…what else you need to know?
