It looks like some recent comment threads have been having problems — the threads are stopping midway and not letting in additional comments in some of the threads posted in the last 24 hours. I don’t know why that is happening or how to fix it, but I have been getting some e-mail from readers requesting explanations and I just wanted to flag that it wasn’t intentional. Just a glitch, not an intentional act. I’ll see if I can fix them, but I’m not sure I’ll succeed.
