I think we're furiously agreeing here. I have no problem with you using the word "theory" there, but I do think some theories have more explanatory power (which I think of as "better") than others, wherever we are on the spectrum I posit from physics to fog. My interests are largely at the foggy end and how to come up with theories with explanatory power at the foggy end is something I'm presently wrestling with.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
If continuing the discussion becomes impractical, that means you win at open threads; a celebratory top-level post on the topic is traditional.
