I gave a talk last night on Silverlight at the NYC .NET Developers Group. We had Powerpoint slides, demos, code, and pizza! Originally scheduled for 6-8pm, we wound up staying much later. We just couldn't stop - a great bunch of folks and some amazing dialog (aka Geek Banter). If you are in the area I would suggest attending the next meeting it was a ton of fun.
