Not as a bridge to other disciplines, or a way to meet cool people. I mean, is the subject matter itself valuable as a discipline in your opinion?
A little bit but it varies wildly based on who you are.
Is there enough to this? Is there anything here worth proselytizing?
Not really.
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.
