As some of you have noted, comments appear to be down at the moment. Typepad, the service which hosts this blog, has been the victim of a criminal "denial of service" attack for several days. This has knocked our blog (and thousands of others) offline. Typepad has scrambled to get things fixed, but - at the moment - the comment function appears to be down. We're hoping everything returns soon. And, to be clear, the problem lies with the criminals who are trying to disrupt the system, NOT with Typepad, which is struggling to fix things. Your patience is appreciated. Note, by the way, that the podcasts (the audio versions of the reviews) are NOT affected - only the blog.
