What tiktok does is curate well. But I often find myself searching for new creators by what I already like. Tagging systems and smart groupings can help me customise my feed on my own but are really hard to do by hand. The problem with algos is that I get no say in what they hide and show. I would love my personal bias to be embedded by myself. The problem lies in who controls the algorithm and what their biases are.
Wood is plentiful. They are testing wether it is viable. This is the only way to find out whether it is smart or not.
