Sorry, readers. Somehow back-links got turned on (I didn't do it) and so every post was followed by hundreds of spammy links back to the current article. I am not sure why I took so long to notice this. I must say that the blogosphere is so swamped with spam sites that searching for anything remotely commercial has become quite pointless. I am sure the tide of spam will once again be pushed back, but in the meantime it's annoying.
