With the direct help of Sam Ruby and indirect help of Justin Erenkrantz, my waste of time is now Atom 1.0 compliant. Yea!
Along the way it went through a ccouple misformats, and some readers picke dup on it during that time... sorry for the apparent republishing of a bunch of stuff. Was accidental.
The tweaked (first by Justin, now by myself with some help by Sam) atomfeed plugin for blosxom is of course, available. Have fun!
