Project Blogger :A company tries marketing commercial products from Nokia, SevenUp, Travelocity by using other’s weblogs. They let you use their products in exhange for your frank thoughts. This has been a concept that has long existed in User Groups. I’m involved with user group programs of Macromedia O’Reilly & New Riders. These companies provide review copies of their softwares and books in exchange for our reviews. It’s smart marketing where both the parties benefit.
