I just want to announce that I will have little energy for this blog for the immediate future. Expect my posts to be brief, though hopefully they will still be interesting enough to keep people reading.
The fact is that my mother is currently in hospital, gravely ill. She was admitted nine days ago, but she has been very sick with a number of problems for the past year. I've just spent a few days interstate, staying at my sister's place, and I think that family worries are going to be my main priority for some time. I also have other responsibilities over the summer break, notably a thesis to finish off and some minor academic duties (just some marking, I think).
Fortunately, I'm not working in a full-time job but more living by my wits ... so I have quite a lot of flexibility, at least outside of the teaching semesters. But writing articles, long blog posts, and the like will have to take a fairly low priority for now.
