Steve Gillmor has an excellent post on Attention.xml and the rationale and use cases for why we developed it together. We're working hard on turning that vision into reality, and I'm encouraged by how many others (look at the people linking to Steve's post) are "getting it" and working on it. This is not a one-man or two-man show, it has to have involvement from a community, and it has to be as open and transparent as possible. Go Steve, go!
