Hi, I think that perhaps there's a way to increase the number of del.icio.us users and reduce spam at the same time.
The idea is to use an invitation or endorsement system with consequences. Given a competitive environment for del.icio.us users (e.g., CollaborativeRank), we could allow users to further increase their scores/influence by inviting/endorsing people who they believe will contribute in a positive way. If those invited/endorsed people do in fact contribute in a positive way (as measured by the competitive environment), then those who invited them are rewarded with greater score/influence. If those invited/endorsed people contribute in a negative way, then those who invited them are penalized. At this point, the "inviters" can cut their losses by flagging these people as unhelpful. Note that I am not necessarily suggesting an invitation only scheme. You could endorse existing del.icio.us users for example if you believe they will raise your score/influence. It would be interesting to see how people might try to game this system. Would creating multiple accounts help for example?
