I did a search from shitjustworks for “reddit die” and did not find https://lemmy.world/c/watchredditdie so I made https://sh.itjust.works/c/watchredditdie (unnecessarily). This should really not happen. When someone makes a community there should be a “ping” sent out to notify all other federated instances.
And from what I know, if I post to !sh.itjust.works/c/watchredditdie only users on sh.itjust.works will see the posts until other people from other instances randomly come across it somehow and subscribe? This really needs to be improved.
Pressure your instance to join https://boost.lemy.lol and pressure your mods to add the community there (or you can add it yourself if the instance is already part of the project).
