Baseball, Beer, Travel, and Running

What Dave describes from Andrew's vision around a decentralized Twitter sounds very much like a Weblogs.com on steroids. What Twitter does really well is aggregate a stream of consciousness from all the people I'm following, similar to the way Weblogs.com accepts incoming pings and shows the latest updated blogs. Using something like RSS with a 140 character limit (Really Short Syndications - natch), it shouldn't matter where my Twitter stream lives as long as there's a ping mechanism in place to let my followers' streams know I've made an update, sorting those updates into a steady stream of information.
