I will admit one thing, we at Microsoft at times have a lot of online brands to cater to the Silverlight, WPF and Expression Studio ecosystem. There are a lot of moving parts to our UX Platform with events, communities etc all having niche requirements.
That being said, there is one that will bring balance back to the force, the new Expression Community Site.
This site is the rally point for all things related to Expression Studio, and if you're not a member yet, become one.
The future plans for this site are big and the team behind the site are working very hard to grow it further and make it into the "MSDN" for designers.
