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.
Yeah, that’s the issue federation for lemmy have. I’m from a very small instance and my “All” feed only shows just a fraction of community from those big instance. If i need more community post showing i need to manually request federation for each and every community. It’s not too big of an issue if you’re from big instance as people will likely look for more community to subscribe, but for small instance it will be barren most of the time if no one try to look for new community using external browser, which makes people migrate to bigger instance, and defeat the purpose of having multiple instance.
Though i must say, manually federating is quite fast these day, i remember last year i have to keep refreshing for it to shows, and it take hours for the content to federate. The dev surely do magic.
For small instances, admins can use tools like https://github.com/Fmstrat/lcs to subscribe to most of the active communities.
