I mean, it could certainly be applied that way, using private relays for instance. Its a protocol that provides a lot of options though, like a more reddit style interface that I'm looking forward to, civkit as a decentralized marketplace sounds awesome. There isn't a defined financial incentive for developing here though, so developers are working as a passion project. It doesn't have the network effect that other platforms have, but all I get out of going to twitter is like 3 cute cat pics then a steady stream of anger.
