Apologies, but all comments will now be moderated!

I have no desire to limit either positive or negative comments here (as long as the comments have to do with the site topic and do not lead to an obviously unrelated page), but I just discovered that some of the (vague but sincere sounding) comments with web addresses are simple spam, leading to pages touting Viagra, etc. I will try to approve comments daily and I apologize for the delay, but I had no idea spam came in so blatantly.  Such is the world of the internet.
