I haven’t mentioned it for a while, but I really appreciate the contribution made to this blog by the many readers who contribute comments. I get lots of useful information, occasional correction and plenty of points on which to sharpen up my arguments. You get the chance to have your say without the hassle of running a blog. So if you’ve been too shy to comment, now’s the time to have a go. Remember you don’t have to use your real name or anything that would identify you.
