After wrestling with the grammar of your headline (and giving up), I must say that I agree. With Dave. When someone thinks as thoroughly about a topic, say RSS, as you have it is difficult for many of us to appreciate the conclusion (your conclusion) at first blush.
I remember learning of XML back in the day and of course discounting it. What good could it possibly hold for me? Then I discovered RSS and then thought OMG that Dave Winer is a genius! Until I learned it used XML. But it did, does, and I expect it will for a long time, solve a lot of challenges. For me and those willing to set aside years (decades?) of wrongheaded thinking. Regardless what is under the hood.
Thanks Dave for being… well, for being yourself.
