What do you mean "no other way to do it"? Traditionally these sort of things been curated, by humans who read and make judgements, how is that not another way to do it? Probably would solve the whole "bit... bland?" problem to, given the right curator.

The approach I tried was to rely mainly on what comments I've upvoted, have the AI look at those comments and gather context from the article/link and the parent comment chain, then give me a "here's what you learned yesterday" brief.

I had plans to add some memory to mention related things from recent weeks. Relying mainly on being able to visually code all this with n8n, and never quite got it working.
