Yapamp is a social portal for people and bands. Anybody can create a new band page, and afterwards there is complete democratic control over the content of the pages.
Video, audio and Images can be posted by anybody to band pages and then democratically rated and commented (a lot like reddit).
The band pages have freely editable and versionable articles (a lot like wikipedia).
Users can follow band pages and other users in order to keep an eye on the things they like (a lot like twitter/facebook).
