For me, one of the most interesting and important web movements at the moment is the decentralized social web. The idea of sharing contacts, profile information and all kind of content between different plattforms, blogs and networks is such a great thing.
The following video explains perfectly what stands behind it and how it works.

I think that it is important for developers to become a part of this and to support the standards and techniques in their projects to tie the different plattforms and networks together.
To make a start on Zootool, I’ve implemented microformats all over the place to make all of your contacts accessible by other sites (you should try identoo to see it work). Support for foaf, media rss feeds and finally the API are the next steps to make Zootool as open and user friendly as possible.
