PieFed is also a nice project, though it doesn't do microblogging so it's more of a Lemmy alternative.
I guess the whole point here is that people come from different platforms - I'm not sure it makes too much sense to include the platform in the community name at all. General names like 'AskFedi' or AskAround' would make a lot more sense in my book. I don't really care all that much which software a community is hosted on.
