In case you wonder why there are so few blog posts these days it has to do with the fact that I have only 1,5 month left of work before my vacation. I have to finish a multitude of articles (nine or ten I think it is!) and work on two books. So my work primarily consists of editing, editing, editing… Not much new input from reading that might be of interest to readers of this blog. I expect there will be around one blog post a week until my vacation.
