Action Streams: An interesting new plugin from Movable Type that will aggregate your actions from 75 different social networking services and publish them as a feed from your MT install.
The Action Streams plugin is an amazing new plugin for Movable Type 4.1 that lets you aggregate, control, and share your actions around the web as well as a list of your profiles on various services. With the Action Streams plugin you keep control over the record of your actions on the web. And of course, you also have full control over showing and hiding each of your actions. The Action Streams plugin, by default, also publishes your stream using Atom and the Microformat hAtom so that your actions aren’t trapped in any one service.
