Text-Only Social Network
When you say "social network", do you mean Twitter Clone?It seems like developers in particular have come to regard Twitter as archetypal social networks despite it's many problems and the way the user doesn't really much ability to define their own social graph. IE, N-character limit is still a determiner of Twitter (poisonous) discourse quality, just for example and Twitter isn't something most people enjoy being on but I think it's what people get on to seem/feel important.I think by earlier terminology Facebook/Myspace/Friendster/linkedin are social networks and Twitter/Mastodon/etc  are "microblogging services".I think the clone-Twitter impulse is kind of terrible. Not even to say Facebook is inherently better but because I don't think ways of defining one's own social network have been exhausted by all the networks out there (Discord is another format with increasing presences which shows that new ways of organizing connections are still possible).
