How to comment (and please do)

The number of comments here has declined dramatically since we were obliged to introduce registration and, basically, use the comments system from our new group blog, Comment is free. Sorry, there's nothing we can do about that at the moment. However, the hurdles are not as big as you might think. First, once you register and log in, a cookie will probably keep that log-in alive. I've only ever had to log in once on this PC. Second, you can open a separate browser window (or tab) to comment, eg by hitting Ctrl-N or right-clicking Comments and selecting Open in New Window. That way you can still see the blog entries while commenting in a separate window. It's not ideal, but it's not an insuperable problem for anyone with a useful and interesting point to put across.
