OK, I'm going to soft-launch the project I've been working on for a bit. This article describes the serialized feeds system I've build on course.downes.ca. The idea of this site is to enable people to create their own serialized feeds. The article describes how I set it up. You can create your own feed here - create a new account first; your OLDaily account will not work on this site (I really want to keep the two separate) but OpenID will. You can also subscribe to the RSS feed I created as a test by going here and clicking on the RSS feed - you do not have to register to subscribe to a course. The article on my half an Hour blog is unfinished, but it's enough to get us started. Your comments and ideas would be most welcome; I have a lot I want to build on to this service, which is (so far as I know) unique in ed tech.
