Techniques for collaborative debating are provided. Pieces of content are associated with particular identities and submitted to virtual communities. The content and the identities then receive metrics as: comments, attributions, and/or reputation ratings from various members of the virtual communities. The metrics are collected in a repository and subsequently summarized for requesters to assist in analyzing the credibility of the identities and/or the value that particular pieces content add to a particular debate within a particular virtual community.
