Wow this is big news. I would love to have Dave Winer and John Patrick kick off the HyperCamp model (which I like) with a debate on RSS verses Atom. John Patrick is an incredible authority on technical trends so when he has something to say I pay attention as do many others.
I am extremely interested in how this plays out because some say the RSS spec is to loosely defined and other claim that Atom is more reliable.
How does this impact Microsoft, Yahoo, and others who are all betting on RSS?
