InsideRIA.com is a new online community developed by O'Reilly and sponsored by Adobe. The goal is to create an invaluable resource for information on the ever-changing state of design and development of rich Internet applications (RIAs).

They first group of featured articles look to be really good. And with lineup of team members I am sure we will see good articles continuing into the future. They will also be inviting guest bloggers in the future. So I would suggest bookmarking this site or subscribe to their feed if you do anything with or have interest in RIAs.
