Huh, I've had a pretty good impression from Beehaw from the limited time I've spent on Lemmy. Granted, I've not actually tried to register there, I just went to Feddit and was approved nigh instantly.

Although it really shouldn't be hard pin down what kind of community they want to build on Beehaw, they have several longform posts about this on !support@beehaw.org

I get that writing these little applications and the prospect of rejection is pretty stressful, it had me worried when I first joined Lemmy, too (although I guess Feddit is/was a lot less picky than Beehaw). Ultimately, though, most of these various instances have to keep a lid on how much they grow since their resources are far more limited than lemmy.world
