Just in case anyone was wondering, I decided not to do part 2 of
5 Features of Good Puzzle Design, just because I was having trouble doing it in any way that didn't end up looking a bit like a textbook. If you were interested, then you probably understood enough about what I was trying to say in part 1 to get all you needed from it anyway.
I really ought to give myself guidelines for blogging to avoid things like this. I think they'd go something like:
1) Only write if I have something to say.
2)
Always write if I have something to say.
3) Don't do reviews.
4) Don't make any promises.
5) Feel free to ignore 1-4 in special cases. For example, if I really want to.
