I turned in the final final final final updates for the book yesterday. That's a load off. In the end it was a lot better for all the help in comments and emails from lots of folks. So, if that was you: thanks!
Why no site updates? I guess I got engrossed in thing itself. Once you've caught upwards of 300 typos and several more serious problems in a thing, that old thing - the draft - starts to look a little flea-bitten. A certain relentless negativism of approach can set in - but in a good way. And part of you just wants people to come back with the shiny brand new final thing is ready. Which will be by early August!
Thanks for all the help with the ms. everyone. It really did make a difference.
