I'm involved in helping form a national user group for Microsoft's cloud computing platform, Windows Azure. A community web site is now up at http://www.CloudComputingUserGroup.com where you can post info, ask questions, and share everything from ideas to code. Check it out!
The user group will also have local chapters. These can be in any location where someone is willing to host the meeting each month and find a place to meet. Microsoft consulting partner Neudesic has offered to provide meeting space in its locations. It looks like the first meetings, which could be within the month, will take place in Seattle, L.A., Orange County (CA), San Diego, Phoenix, Denver, Dallas, and Philadelphia. Thank you Neudesic!
Cloud Computing is a big thing, and it's going to take a community to pioneer it.
