I will post more on this in the morning, but I wanted to get a quick post up before I go to bed.
First, we just announced that we have joined the Eclipse foundation and are working on an Eclipse based IDE for creating rich internet applications (code-named Zorn).
Second, we have launched a new section of our website focused on the Flash Platform. Tons of info here. For starters, make sure to check out the Flash Platform white paper written by Kevin Lynch.
You can visit the Flash Platform center here.
