Mark Cliggett's blog seems a good source of information on our Community efforts. 

One of the interesting aspects of these changes is that it's not uniform.  You're dealing with many different people, so each one's personality is going to shine through.  We also have a lot of other responsibilities that don't go away just by blogging or reading a newsgroup, so we'll come & go unpredictably.

But you at least know you're dealing with the real folks who work directly on the product.
