Radio Userland has been upgraded to support Really Simple Discovery (RSD), an XML-based protocol that enables weblog editing tools to easily find the Web services they can use to read and write a weblog.
That’s probably what caused a nasty 500 Internal Server Error when I booted up the weblog this morning. I have a feeling that the mail aggregator root update got hosed at some point, as I had to comment out mailAggregator.init() or something in order to get Radio to work this morning. I need to wipe the system that Radio is on and restore, but I’m afraid. I’m subconciously putting it off as long as possible.
