While at the PDC I ran into my good friends who work in the "Federal" group at Microsoft. They are responsible for developer and platform work specifically for Federal projects. They are trying to get the word out about their new blog which is for anyone building mission critical solutions for the US Federal Government. They are *very* intersted in seeing projects for the government be successful and will have useful information and an open communications channel to people with lots of rich knowledge.
