Scoble gets taken in by Winer vis-a-vis the RSS Advisory Board:

But, what really is cooking here is that RSS has been given (and if you listen to Dave Winer, stolen) to big companies to control. How so? Well, the RSS Advisory board, which includes members from Cisco, Yahoo, Netscape, FeedBurner (er, Google), Microsoft, and Bloglines and this new unofficial board +is+ changing the RSS spec all the time (they are now up to version 2.0.9). Dave Winer, who founded that spec says that’s in direct contradiction with the original charter of the RSS Advisory Board that he founded when he moved RSS from UserLand over to Harvard University.

Maybe Winer is too close to the problem. The advisory board isn't making many changes; I've been following the process. What they have been doing is setting up a set of "best practices" for using RSS 2.0 - things like "the spec isn't clear about X, but here's what seems to be standard practice".

For instance: Can a feed have more than one enclosure? The original 2.0 spec is completely unclear on that. Some aggregators (BottomFeeder, for instance) are agnostic, and will allow multiple enclosures. Others will allow for only one. Most of what the advisory board is doing is finding agreement on what to expect in the unclear areas.

Why do big companies care? This thing called interop, which Scoble does care about. Watch him not connect the dots on this.
