Cylive (http://www.cylive.com) is a "social publishing and networking application". Cylive lets you store & share; produce & publish ANY content in a social, collaborative
It gives you the freedom to personalize the content that you publish - for instance you can upload photos with a attached audio clip about the story behind the photo. Or, you can upload a music video with the music sheet & the lyrics attached. It truly lets you mix-n-match, slice-n-dice content pretty much any which way - in other words, it lets you mashup "content-types". It also has cool "access-rights" functionality that lets groups collaborate.
