On your homepage you call it a "social learning platform." The title tag calls it "social publishing for groups and individuals." Further down you say, "you might call it a publishing platform." And Github calls it both a "social publishing platform" and a "social group platform."

Aside from a vague WYSIWYG box in a wireframe, the only thing that seems to tells me what it actually could be used for is the Unified Comments block. That sounds interesting but it isn't clear how it fits into the learning/groups/publishing focus.
