In particular, it seems to me that centralization is almost a law of the universe (or at least a tendency). Lemmy may start decentralized, with dozens or hundreds of meaningfully-sized instances, but it’s easy to imagine a not-far future where most everyone has settled on just a handful of instances (or even just one).
I don’t mean to just be a pessimist here. I’m sure I’m far from the first person to wonder about this, and I’m curious whether there are ideas of how to counterbalance the tendency toward centralization.
Yeah definitely the key to decentralization is having the minimum amount of action on the instance level. Everything should be either directed within a community, or to lemmy generally. Might be a good idea to even get rid of the “local” view level - or at the very least not make that the default.
