For the first time in the four years of this blog I've received a series of mean-spirited and highly critical comments. I've deleted his comments not because they are critical (there are plenty of critical comments on this blog!), and not only because they border on mean-spirited name-calling (which they do and which is reason enough to remove them from this blog). Primarily, I've deleted the comments because the author didn't sign in with a real email address nor did he leave a web address for his own website/blog. Not leaving me with any way to engage him directly, I have no interest in dealing with his comment vandalism on my blog.
