the notion of nostr as merely a reimplementation of twitter is a misunderstanding of what the protocol can do

probably the kind one, globally replicated feed will continue to exist and will grow so large that it mainly is provided by a small set of scale capable providers like nostr.land and nostr.wine

but small relay clusters and single relay based communities and apps to serve them are increasing in number as time goes by, and it will be in those conditions that the original nostr vibe will continue to exist

the difference will be that people will be able to be members of multiple, relevant communities with a single client instead of there being an abject gulf between them. people will be able to quote posts from other communities and have them appear in other communities, for example, this is something that the old school forum BBS couldn't fix, and partly how we ended up with these giant monolithic online social network cities like twitter and facebook.

comparing nostr to these highly scaled, but siloed social networks is like comparing trains to horse caravans. in principle they are similar, but they only are common at a high level of abstraction. just like the internet is like book and music publishing, it is far more than that, because of its symmetric connection to users. nostr is the continuation of a trend on the internet towards thinner membranes between connected systems. it has the potential to obsolete the isolation of systems, like, you have to pick - telegram, slack, discord... or twitter, reddit, stackexchange, facebook, instagram. each silo binds to a local identity and this identity cannot be carried from one place to another, the links across between the islands is very narrow and cumbersome.
