I'm happy to see that Steve Rittler, long time Philly CFUG manager, has entered the world of blogging with his State of Independence blog. Steves a really great guy, and an excellent developer. Although his blog isn't specific to MAcromedia technologies (it's built in ASP.Net), Steve has a lot of insite to offer on both ColdFusion and Flash development. Look for a lot of good information from Steve in the near future.
