Just a quick note before I go and try to slay the writing dragon: If you've made a comment here and it hasn't shown up, it's not because I've deleted it. Sometimes there's something wrong with the comments mechanism--even my comments haven't appeared when I've pressed the "post" button.
So feel free to comment here--and there's no need to write in correct English, either (in case the non-native English speaking readers want to post something).
I'll do a proper post later--right now I've got non-blog stuff to do.
