I don't think that'd be a good idea. Less is more ultimately, and the less users have to choose the better. Think of it this way, they already struggle with picking a federated server, so choice is hard. Ideally a good algo should be able to balance that, and I think Reddit's algo is pretty good about that. I know they used to open source their algo, and Lemmy bases their Hot feed off of it, but I think they definitely have changed and tweaked it since then. But, for the better anyways.
