Lots of activity in the last week on the distributed social networking front.
Check out the Prologue Demo Blog for a sense of how the theme works. This could easily be used to create a kind of workgroup twitter, and given the number of different plugins / mechanisms for creating a blog post it could be extended to mobile, IM, and other integration points. The important difference, of course, is that you’d be hosting your own experience, not relying on Twitter – though that also means you’d need to build your own audience.
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.
Both of these represent significant advances toward an open source, open standards, portable data approach to social networking and lifestreaming.
Since the implementations are open source, expect similar functionality to be ported across platforms.
