It would be nice to have a tiny store online that could just sit there for decades.
Focus on one tiny and useful need and do it well, world class.
Sell one or a few tiny products or services for that one thing.
Not a full time thing, free content, self-serve product sales with on-demand support.
I guess SuperFastPython fits the bill, but even it’s scope is too large.
Ideally one thing. One algorithm, or one data structure, or one library/module.
A micro-authority site I guess.
