Hmmm. When I looked at RSD nearly five years ago, it didn’t seem so bad. In any case, here’s a ticket and a patch to get WordPress to support autodiscovery of AtomPub endpoints.
[Here, here! And the peasants rejoiced! And the reason one (influential) person in the Atom community didn't like RSD wasn't for technical reasons, but because Dave Winer is an acquaintance, and an early supporter of RSD... and he was reviled by some members of that community. Anyway, all these years later, RSD is quietly doing its job, and should be employed for this purpose. That was kinda the point, with no preference for one API over another. Thanks Sam!]
