Dell got a fairly bad rap a while back its treatment of famous blogger Jeff Jarvis. Dubbed "dell hell," it has become a case study in how bloggers can have a true impact in commerce.

Fast forward almost three years and Dell has really turned the tables in many respects. An item in the Wall Street Journal tells a pretty cool story of Michael Dell getting the blogosphere to work for him in an effort to launch a new product. I think this is a very good example of social media coming full circle within a corporation.
