Microsoft quietly launched an experimental social network called So.cl, pronounced "social", is an experimental research project, developed by Microsoft's FUSE Labs, focused on exploring the possibilities of social search for the purpose of learning.
Users are encouraged to search for information about a particular topic, then compile the best results - textual content, images and videos - into a single post. So.cl is initially targeted to students. Microsoft is calling So.cl "an experiment in open search," in that anything you search for on the network is viewable by other users and made available to third party developers. You can sign up using either your Facebook or Windows Live profile. So.cl is something called "video parties." This is basically a video playlist with a chat area.
