I haven't been able to put myself into concentrating as much as I'd hoped. However, the other thing in my life that had set that hard target has also ended up pushed back by a week, so there's still a possibility it'll get completed if I can get it done during the next week. I've made a start on the "expository" part of the blog, which has thrown up a couple of "layout" questions that I'd like your input on, that I've asked on the new thread for that blog entry.
