ReadWriteWeb

All blogs on the WordPress.com platform and any WordPress.org blogs that opt-in (using this plug-in) will now make instant updates available to any RSS readers subscribed to a new feature called RSSCloud. There is currently only one RSS aggregator that supports RSSCloud, Dave Winer's brand-new reader River2. That will probably change very soon. Update: Within hours another RSS reader called LazyFeed has announced that it will support RSSCloud as well.

RSSCloud is an element that's always been present in the RSS 2.0 spec but has drawn new attention with the rise of interest in the Real-Time Web. The element was just added to the WordPress code this afternoon. The implications of this big vote of support go beyond reading WordPress blogs; this is the kind of traction that new technologies can leverage to gain support in many different applications.

Google Labs just launched Listen - an "audio magazine" that allows Android users to subscribe to programs and search terms to queue up their podcasts for easy listening. While Listen only offers English audio podcasts for now, the company plans on expanding to index video and content in other languages in the coming months. The product allows you to keep a couple hours of audio on your phone for your daily commute, lets you share podcasts with friends, and helps you find the latest updates for breaking news stories.
