Apologies if you've recently posted a comment on this blog, and had not heard back from me (I try to respond to all comments whenever I can). Seems that my Gmail account for receiving comment alerts began flagging them as spam. Seems the address for comment alerts was also not among my contacts. Seems odd to me, though, that two Google-made products would suddenly butt heads like that. Seems like they should know better.
Anyway, I'm back on track with comments again, and I've just posted a bunch of responses. So if you were looking for one, check for it. It should be there.
