I concur and am actively researching this issue as well. I, for example created my own instance but am not entirely sure I should be the one to host yet another Selfhosted community. I am hoping for a dominate 2/3 of them to win out, preferably lemmy.ml as it was the first I discovered. Alas, you asked a very pertinent question that I think you should keep searching to find. I did see the owner on Lemmy.world actually responding to his thread…
We should absolutely instill the desire to keep this community alive though.
