In what I'm sure is going to become a fairly popular site, Microsoft has just published the MSDN Product Feedback site.
Have an issue with a dev product? Tell them about it. I will be interested to see how those stats keep up - Right now, bugs closed is higher than open bugs. That's a good sign!
I actually run a similar statistic for some of my own projects - we send it out every morning with an overview of what issues each person has assigned to them.
Transparency is great - as long as the egos don't get involved.
