I like it, but I also can see some issues with it where communities grouped together may have different rules and standards for posts or comments. Even on kbin it's hard to see what instance a user or thread is coming from so keeping track of multiple rule sets across domains could be tricky.

By any chance are you autistic? Many autistic people report that sedatives and stimulants have opposite effects for them, with sedatives leaving them wired and stimulants leading to them becoming tired. I had a similar issue with benedryl as a kid.
