I've added the annoying word-test requirement to comment. I'm spending more and more time cleaning up spambots in the comments. My regular readers (both of you) will just have to deal with the inconvenience. Sorry.

I'm not sure what it is about 2 posts in particular that make them such spam magnets, but oh well, many and mysterious are the ways of script kiddies and spammers...
