Okay, although I'll probably roll this back if they come to their senses, I'm not expecting that; I'm expecting to be leaving Twitter pretty much completely. That makes the thought in the back of my mind that I need to choose a new instance here, somewhat more important.
Instances are absolutely not "communities"; they are infrastructure for accessing a larger network and as such, it is imperative that they be neutral. As such, a "themed" instance is probably not appropriate for me.
