Or maybe it’s me the one who’s clueless. I don’t see how the (not)Echo project stands to damage Mr. Curry in the least bit. RSS 2.0 will continue to be supported by aggregators for the foreseeable future. Even if it wasn’t, changing to a different feed format is trivial. I’m supporting four different formats now just because it was easy to do so. As I understand it, it should be just as trivial for Adam to do the same with Radio.
