Syndic8 now supports Atom. Heck, BottomFeeder has supported it (both 0.2 and 0.3) for months now. This is creating a problem though - Atom was supposed to create a single, well specified format. But wait - Blogger is now pushing Atom Feeds. What we'll end up with is at least 3 (and probably more) variants of Atom, starting with 0.2. The end result will be every bit as confusing as RSS has been. I'm hardly the first person to notice this - Charles Miller commented on this a few days ago. The spec is still being argued over, and clients (Bf and other news readers), search tools (Feedster) and web based clients (Bloglines) are already supporting it. The unbaked 0.2 and 0.3 formats are now going to live forever - because no format ever dies on the net.
