If you have never used BNET, it's time to start. The site is owned by CNET, and got started as a directory of business white papers. BNET management quickly realized that a white paper directory wasn't going to attract the audience they wanted, so they revamped the site entirely. In addition to a very cool design, the functionality and content show a lot of thought and analysis about their target market. It's a great place to get started when exploring new business concepts, so give it a whirl and see what you think.
