I don't have a dev answer, but in case its relevant, I've seen commercial services that I imagine are doing something similar on the back end-- ground news is one of them. I wish they had monthly subs for their top tier plan rather than only annual, but it seems like a cool product. I haven't actually used it though.

What feature(s) of the top tier plan do you wish you had? I have no idea how their subs work but have seen a few ads for the product so have a vague idea that it rates news for bias but don’t see how that would involve many different tiers of subs.
