I thought about how apps like tiktok and instagram essentially build up an automated timeline just by watching you scroll, i generally know how that would work, but it would probably involve lots of tagging of posts.

I looked into autotagging posts using an MRE, and I actually tried the Mistral LLM, asking it to write automated tags for my posts. I gave it two examples and then fed some random posts to it, and it worked really well. This might be a good way to build a purely server-local algorithmic timeline.
