Yeah, it's kind of weird. The technical (and many other discussions) are often quite insightful here. It's always fascinating to get into some obscure topic and have a world-renowned subject-matter-expert suddenly drop in to give their two cents or clarify what they meant in some quoted piece.
I'm quickly learning to just steer clear of the political discussions though. They're usually a very jarring reminder that intelligence in one or several areas does not preclude intellectual dishonesty and intentional ignorance in another.
