A new acronym that you'll see myself and others using more of now is VSX, which stands for Visual Studio eXtensibility (and sure is a lot easier to say in conversation!). There's even a new URL you can use for accessing the VSX developer center: http://www.msdn.com/vsx
One of the first things Ken has done is set up a team blog for us folks who work to make the prospect of extending Visual Studio easier and easier. There's already a few videos up there including a clip of our Program Manager, Valery and Test Lead, Deep, as they were uploading the Orcas Beta 1 SDK to www.vsipmembers.com yesterday afternoon.
Since Ken is new to the team, he hasn't met Dr. eX yet. (I've only seen him once...and even that memory is a little foggy now.) He's apparently going to attempt to track down Dr. eX for an interview. Good Luck, Ken!
