Since there seem to be some new regular readers of this blog, I will repeat an offer that I have made a few times before - which is to answer questions from commenters (one question from each!).
Because the daily blog has been running for nearly 13 years and has over 8000 posts; I may well be able to point at some previous thing that has already addressed the question.
Or else, if the question is relevant, and I have something to say on the subject, I may be able to provide some kind of new response.
Anyway - that's the invitation.
