I would be interested in these public lists, like:

• character - accounts that do a bit, e.g.: operated by a fictional character
• subversive - those who advocate political tomfoolery
• on-cnn - accounts that have been on CNN
• aggregator - accounts tend to mostly reblog, they're almost like feeds themselves
• services - represent products and/or services, not necessarily blockchain-based
• financial - financially literate

A really nice future feature would be a way to intersect multiple lists. E.g., an aggregator that is financial. Or subtract multiple lists. E.g., a service that is not on-cnn.
