RESTLog API
Timothy Appnel: If you havn't seen it, Joe's prototype and RESTful API can be found here. A RESTful API for updating weblogs is a good idea.
Overall, I'm positive on the notion of a Well Formed Web... though I would actually rather see a Valid Web. The ability to automatically discover and generate dynamic or static proxies is a powerful notion. One that need not necessarily require that all methods are POSTs or that actions be embedded inside the data.
