Ascent Stage: The National Museum of African American History and Culture

This functionality, called the Memory Book, permits site visitors to compose and upload their own “memories” about anything having to do with the African American experience. The posts can be tagged and are plopped into a visualized web of topics and other memories, forming what is hoped over time will become a rich, dense tapestry of interconnected stories.

Is this a good resource for your project? I was surprised at the technical and artistic quality of the first item I tried: Timba and Teletha, an audio piece.
