Yeah, I think topic based relays, perhaps using an LLM to filter by relevant-ness through 3+ degrees into a social graph, will help with this. LLMs look to be fairly good at this from simple testing.
Topics like outdoors, food, sports, travel, economics and etc could be navigated pretty easily in an app. In-app configurability here I think will be interesting.
If someone is watching a sports game, they may want to have a feed that is filtered specifically for it being related to that game for example. The next day that feed won't be as relevant.
