A few weeks back I signed up for the new W3C working group for what will most likely be called HTML 5. As a change from past W3C practice, this working group has relatively open membership, and the current membership is well past 300. At first the flood of voices on the mailing list was a bit overwhelming. Started picking out “voices” after a bit - sets of belief based on particular points of view.
There does seem to be some measure of convergence. Though I am not at all sure that consensus derived from some sort of average of the viewpoints offered is going to yield an especially good result. Compromise is not necessarily a good design principle.
