Dave Winer suggested to me to start a mailing list for developers that want to support RSS 2.0. I looked if there would be an existing list for this purpose, but coulnd't find anything. RSS-DEV is a lot about developing a standard, and also has to much traffic. So I created a new list. RSS2-Support. The description is:

If you are a developer, and you want to use RSS 2.0 in some way (reading or writing), you can come here to ask questions. This is not a list for long discussions! Let's focus on productivity.
