you know, it doesn't matter if we use #pleroma or #gnusocial or #friendica or #mastodon etc. (are there more we can connect with?). the important thing is that we can communicate with each other. therefore we should rejoice over every additional server that springs into life, no matter what software it runs. whenever the media hypes something that is part of the #fediverse, it's good for all of us. but maybe we need a new name for the whole thing? I feel like "fediverse" doesn't cut it.
there are mainly two protocols out there, the fediverse and the federation (the protocol originated by diaspora). The federation now regroups 5 different projects. Have a look at https://the-federation.info
