PC Magazine’s Top 99 Undiscovered Web Sites include some sites we were familar with already, like StopBadWare.org, TechCrunch, TechDirt and Britney’s Guide to Semiconductor Physics, but many of them were new and, in some cases, extremely different. In a good way. FindSounds.com, for instance, is particularly cool, in our opinion, allowing users to search for all kinds of audio content. NNDB.com aspires to be to world culture as the Internet Movie Database (IMDB.com) is to movies and the movie industry. And 10×10 features the 100 images that “matter most on a global scale,” updated hourly from influential news and opinion sites.
