Earlier in the week, I explained why Facebook Comments are important. Clearly others agree as Facebook announced launch partners for three verticals: commerce, media and sports. I am excited that ShoeDazzle (a Polaris portfolio company) is part of the launch. Considering ShoeDazzle's strong, active community and deep Facebook ties (725,000 Facebook fans!), Facebook Comments is a powerful two-way publishing platform.

Also worth noting: Facebook's specific call-out to the commerce category is strategically and directionally revealing. You can follow Facebook + Commerce at Facebook.com/commerce.
