I hear ya. I don't know the first thing about what goes into running a big instance like that, so I'm willing to keep an open mind. But I really like this instance for its open approach. It fits with my understanding of how the fediverse would work, especially when some of the bigger instances were (at least initially) encouraging people to not all sign up on the same instance to balance the load of new users. By defederating, it kind of negates that aspect. People are going to need to sign up on multiple instances or just go straight to the big ones to ensure access to those communities.
But with everything being so new, I get it. It'll be interesting to see how things evolve as the fediverse grows/ages. I do hope the block list gets reconsidered soon enough though.
If you're a fully committed side sleeper, a tent with a nice sleeping pad is probably your best bet for a reliably comfortable night.
But, if you want to give hammocks a try, I agree with what others have said about laying diagonally. I definitely prefer sleeping on my side and the Blackbird Warbonnet hammock has become my go-to for overnights because it's designed for a diagonal/asymmetric hang and keeps you relatively flat when you get the hang right.
I will say, it took me a few tries to understand how to get the hang right on my Blackbird XLC, since you need the foot end to be like 16-18 inches higher than the head end, which was strange for me since I primarily used more basic gathered end hammocks before. But once you commit to that setup, I've found it to be really comfortable.
Other companies also make similar asymmetric hammocks, like Hennesy, but I don't have any experience with theirs yet (though they look really nice and get good reviews from what i remember).
