I find it helpful to listen to .mp3s of people talking about something I'm interested in. I can focus on that and drift off to sleep and wake up not even realising I fell asleep. Also, I've found a hindu mantra that helps sometimes. It's so hypnotic, it just carries me into the navel of sleep.
From what I can tell, .world is the main, biggest instance with the most people. That means whenever there are technical problems or waves of new signups, things tend to get a bit glitchy due to the system being overloaded. .ml seems to be a computer tech themed instance that doesn't have so many people, so there's not so much to overload all the circuitry bits.
I spent a month getting an instance set up on .world, wearing my account in, putting up with the lag and other constant problems... then I read about this threads™ nonsense and how .world were playing a "wait and see" game with an evil empire. Read this thread (heh!), moved to .ml. Much smoother and more glitch-free experience. Just have to start over again. So far so good!
Yep that's exactly it. Cheers.
