Starting up is always hard. Short of copying over a subreddit to a declared official new home (which did happen for a few), you have to build up from nothing. I think it’s come a long way in only the last few weeks. I’ve already seen a post complimenting the response time and answers from a Lemmy community when the Reddit posts went ignored, and also I’ve seen one community owner realize that the other communities of similar names are doing much better and decide to close up. Another group decided the best solution was not to try and pull in other communities, but act as a general discussion that also served to link up the many specific niche communities distributed throughout Lemmy and Kbin. Lastly the attacks on .world and .ml serve as a reminder of the benefits of having duplicity. What if one of those had been a long-time established home of a community with millions of posts and got wiped from such a thing?

This is evolution in action, what works best will prevail, and part of that will be redundancy and adaptive ability.
