Our list of the new and/or undiscovered Web sites that have grabbed our attention this year. You'll see a large collection of Web applications and tech sites, excellent blogs, offbeat social networks, and, as always, a handful of addictive Flash games for those slow days at work. Some of these sites are completely under the radar and get very little traffic. Others are hugely popular within a specific demographic. But all of them deserve to be in your bookmarks.
