I'd like to see a way of comment aggregation, eg for 1 article there are comments and duplicate articles at multiple degrees of separation: - Article + same story elsewhere on news site + each one's comments - Blog reference to article + duplicate references on other blogs + each one's comment - Digg + competing social news sites + each one's comments - Social network references + other social networks + comments - Comment communities, eg co.comment - Friend aggregators eg Friendfeed and competitors + their comments Would be great to see framework or system to see all discussion in 1 place, not necessarily forcing users to discuss in 1 place, but to see from a historical perspective the different viewpoints. Maybe some type of tag that an original author can insert. Trackback V2 perhaps.
