O’Reilly publishing has just launched their new site, Inside RIA at insideria.com.  This site offers blogs, tutorials, and overall pointers for the world of rich internet applications.  For many years O’Reilly has been the leader in tech books, now they seem to be making a strong push with this site to be more than a publishing house, but rather a player in the RIA community.  So check out the site and give them your feedback.  There can never be enough quality sources of information to help us in our day to day work.
