Threads’ new ‘Dear Algo’ feature lets you tell the algorithm what you want to see by Jay Peters

To use the feature in a public post, type “Dear Algo” and then a description of what you want Threads’ algorithm to show you more of. Once you make your request, the change will stick for three days so you can see how it changes your feed. If you want to see more of the new content in your feed over the long term, interact with those posts.

It sounds like a good feature - a good use of LLMs. It is still opaque though.
