On person grader/social inbox, I'd like to be able to create lists of people by tagging them. Specifically, I'd like to be able to create a list of leads, a list of suspects, a list of leads, a list of customers, a list of partners, a list of co-workers. I'd like to be able to model my funnel somehow where I try and move people from suspects to leads to customers/partners. A simple graph of growth of each list over time might be sufficient.
