Comments and the possibility that they have in some way become unhelpful...

Apparently quite a few people are having problems posting comments - I don't know if that's just for my blog, or for Blogger in general. If you've had trouble, would you mind letting me know at simondavidthomas[at]yahoo.co.uk, just so I know the scale of the issue! And if there are any comments you'd like to make, and can't, I'll post them on your behalf :)
