yes, I would like to be able to quickly assess where a profile lands on that spectrum, how it changes over time, graphs to visualize how different profiles compare, etc.

besides just passively collecting this sort of data, I want clients to offer tools that cater to a user's desire to operate as a consumer, producer, or somewhere in between as they see fit

I'm currently developing a client that does just that. it encourages the productive side by loading new notes only when I post something. that's just one example of how a client can bias towards a particular mode of operation
