Announcing: Audio.Weblogs.Com. It shows the newest podcasts, in reverse chronologic order, the same way weblogs.com shows the most recently updated weblogs. Now you can sample the work of the podcast community before installing an iPodder app. Podcasters, you can ping via XML-RPC, the same way you ping weblogs.com (all the major weblog apps are compatible) or through a Web form.
Podcasting に Dave Winer がからんでるのは既報どおりですが、weblogs.com に Podcasting 用の Ping サーバと Changes.xml (RSS2.0)ができてました。もちろん changes.xml には enclosure つきです。
