Interesting. I feel like long term stability, up time and performance would be valuable to many users. In many ways I’d say just going on to mastodon.social is a bit of a cop out as it heavily dilutes the decentralised structure that is arguably the point of all of this. Multiple paid instances would be healthier. And there, as a user on a relatively peripheral instance but one that is paid-for, longevity and stability become increasingly valuable.
Otherwise, instance providers putting the work into trying to provide a relatively “complete” fediverse palette of tools while making it as easy as possible for the users could also be interesting.
