Longevity.

100% percent! This needs to be taken into account.

Migration.

I definitely think account migration should be improved, but I wonder how feasible that is, in a technical sense… I don’t know how that sort of data is structured at all.

Federation/Defederation

That’s a good point. Once again, I really don’t know of a solution to this. I’m not too familiar with how federation works, in a technical sense. Servers definitely should definitely make public by default their blocked servers and whatnot, though.

Privacy

Of course, it’s impossible to make sure that every single server is safe. My point was that, if everyone is in the same server, then the risk of something going bad for any number of people increases, versus if everyone is in a bunch of different servers. I guess it’s a balance between the trustworthiness of many people with control over a few and the trustworthiness of a few people with control over many. Maybe it’s not so relevant. Most people don’t care about privacy anyway, I was just trying to make a point about why decentralization should be valued in a practical sense.

Yeah, there’s a lot of things that still need to be improved!
