Humble apologies are in order. I haven’t been moderating comments in a timely manner. I was attending the CNI spring meeting and I didn’t take my usual laptop. I confess I don’t have all of my passwords committed to memory (does anybody?). They’re encrypted in a password manager on my usual machine. So I wasn’t able to log into this blog to approve the thoughtful commentary on my last post. Please accept my apologies for any inconvenience. I’ll be sure to memorize that password before my next bout of business travel. My sincere thanks to those who commented.
