word verification activated

Because of the increasing number of spam comments on this blog, I've activated the word verification system provided by blogger. This will force commenters to type a word into a field before publishing the comment. This should stop automated comments. It is sad that we have to do this, and I think it must say something about our society. I will let you decide what it says though. Please don't stop leaving comments though, even though it is a few more keystrokes.
