In case anyone in RSS-land hadn't noticed, Sam Ruby's set up a Wiki to work on a conceptual model of a (web)log. Quite a mixed bag of luminaries have asserted their support. This may lead to a successor to RSS that everyone can agree on (working title is 'Pie' as in 'easy-as'), or it may just be an interesting exercise in analysis and group dynamics. Either way it's significant to the ThreadsML initiative - if something does come out of it, ThreadsML needs to be able to operate with it from day 1. The analysis will be worth watching as it certainly treads into ThreadSpace, we could learn here. I have plenty of personal reservations, but I've been reading Sam's blog long enough to trust his approach (smart guy too), and I think this is almost certainly a (rare) case of it being better to influence things from within.
Sam's trying to address one issue at a time on his blog (just started with the about/link/guid/URI stuff) :
