On the road

I would like to apologise for, and explain, the erratic (or perhaps I should say more erratic than normal) updating of this blog in recent weeks. I have been on the road, literally, in the US and for much of that time, have been unable to get an Internet connection. Normal service will resume in due course, for better or for worse. I hope I'll also be able, eventually, to produce something explaining what I've been doing here.
