PDC Bloggers and PDC Underground

I am going to attend Microsoft's Professional Developer's Conference (PDC) in Los Angeles this year. Though I was contemplating it skipping it after the disappointing initial announcements regarding Microsoft Visual Studio.NET 2005, the content looks great and the developer tools story is improving so I changed my mind. In an upcoming blog entry I will list my breakout itinerary, but there are two sites I just ran across which are pretty interesting:

• PDC Bloggers
  This is a site which filters news from the media, Microsoft bloggers and geek bloggers. It provides a steady stream of interesting content about the PDC. I just registered "Dispatches from Maine" on PDC Bloggers since I plan to write quite a bit about the breakouts while I am there.
  
• PDC Underground
  What on earth is this? It sounds like a cool geek party with possibly worthwhile content. I might register for it.
