Who will make this push? The problem with adoption of the text only standard would probably be that the generic browser will support that use case just as well as the simple browser. In general it would be hard to choose between one or the other world. Rather than that, how about offering a very simple CSS on top of RSS? So that feeds could be personalized a bit, should the clients choose to support this?
