Corporate sites benefit from user communities.

I've written and produced a few pieces about how companies in the B2B space can benefit from Web 2.0 principles and technologies. Take a look at some of the points made in this recent AdAge Post. I particularly liked this point:
"Visitors to [corporate and brand] websites have a much higher propensity to recommend products," said Pete Blackshaw, chief marketing officer of Nielsen Buzzmetrics, whose research shows more than 40% of people who give a brand e-mail feedback are likely to recommend it to others."

Companies can benefit from the creation of their own user community.
