A great tool for checking out new sites (and wasting time) is the StumbleUpon Firefox extension. After you download and register, then choose the genre of sites that you like to view. Then when you hit the Stumble! button on the Firefox toolbar, a new site will appear. You can find sites that are recommended by other registered users. Its a great way to discover new sites that wouldn’t come up in the search engine search results and that are organized around genres. You can also view profiles and recommended site by “stumblers” or community members.
