Dave Winer: Just got off the phone with Steve Gillmor. He asked about yesterday's post about publisher-opt-out for RSS. I wrote up a proposal approx two years ago. Yesterday Adam had an interesting idea of how to do it. If a feed has a very large ttl value, then go ahead and unsub. I like that approach. Nothing new has to be invented or documented.
Randy: The above both seem like a bad idea. Many RSS readers, like my Juice browser are already implementing the 410 Gone solution. This solution for tearing down a subscription channel is not a new invention and is well documented. Nothing new has to be invented or documented. And it's already implemented by many RSS readers.
