That perfectly describes my reaction as well.
Yes, I'd also be interested in those docs, Tal, if you conclude that it's OK to release them. Maybe this is self-serving of me, because it justifies something I want, but I can honestly see the info you described as being part of the historical documentation of this project. As such, those notes would seem to be a reasonable part not only of the dump of LT code that Josh promised, but also the Book About LT promised in the Kickstarter.
Naturally I'd agree with you redacting personal comments and any other remarks that have nothing to do with LT as a project. It would just be nice to get a sense of Josh's perspective on LT's features as The End drew nigh.
