Welcome to Tuesday's Open Thread. I'd like to begin by first thanking QMS for all the wonderful and thoughtful essays he's written during his tenure as an Open Thread contributor. I will miss his Tuesday morning musings and his humor but I can also appreciate the demands that life and work place on us at times. Stepping in for him, especially committing to weekly postings, gave me pause. What if I don't have anything interesting to say that week? Then you'll show up and do the best you can, a friend of mine reassured me. And that, as they say, was that. So, let's see what happens, eh?
