When Dave Winer says that RSS is going to embrace Microsoft, he's right. So far we're listening to what the community actually uses and haven't gotten ahead of the community (which includes publishers like the BBC and the New York Times) and tried to tell the community which way to go. I think that's a good thing.
That said, our RSS platform is reading in Atom too and we'll support whatever the community adopts. Hey, has that Jeff Sandquist guy (aka my boss) been fired yet for supporting Quicktime and PSP? No!
