A few folk have noticed that my sidebar linking other blogs has been updated and have asked (off blog) about some of the changes. 

Now and then blogs become 'defunct' because their authors find better things to do with their time.  Other people decide to delete their blogs for various reasons.  Occasionally I feel that my interest in a blog probably isn't shared by my readers. 

This is just to say that I have removed links to one or two blogs on this basis today, and please don't read anything sinister into it!
