A note and partial apology
Spammers found my other blog and it will only be a short while before they infect things here. In order to comment on this blog you will now have to verify that you are a human being and not a computer program by demonstrating that you can recognize a group of random letters visually, something computers can't really do yet.
Sorry for the inconvenience, but having spam comments all over my blog is even more inconvenient for all of us.
