There could also be /m/Technology on every kbin, lemmy instance as well. Now if the mods from Reddit are moving over I could see that as more “official”.
That’s also what makes the fediverse options great, they each can be used together and separate giving users a wider use case of one instance over another. If they like the community in one but not another. Or if one community leaves the whole thing is not gone.
One note too on the “unofficial” list is the way each platform recognizes and is searchable for them is different on each platform. Be aware if you “can’t find it” using the way the community name is listed.
What is hard too, is if all the posts to get things started are the mods or creator, the same ghost town might occur. It’s hard to tell or know what will be interesting to get people talking so to speak. Some should also be put on the subscribers as well who also have an interest. It’s a double edge sword sometimes.
