Well that was surprisingly conclusive...

- ie the views folk were kind enough to express on book titles. Both here and on FB, there was a definite vote for Using Glass Like Air, with several people saying it would be oddball and intriguing enough to make them buy a book. I might hold you to that... seriously, that was a very helpful exercise, because I'm too close to all contenders to have a clue what resonates or doesn't with others. Using Glass Like Air it'll be, then.
