AtomEnabled is the new site for everything about Atom. There is a special area for developers with detailed information. Last night Blogger announced support for Atom. I have an Atom feed. I tweaked my RSS feed a few times, and now that Atom information is more easily obtainable I might start tweaking Atom a bit as well. After tweaking my feed makes its way through the FeedValidator to make sure everything is well formatted. My Atom feed gets less hits (6% of aggregator traffic) than my unpublished (Meta reference only) RSS 1.0 feed. (11%) RSS 2.0 accounts for 83% of all aggregator traffic to my site.
