I thought this puzzle was a great idea very well put together and as such I enjoyed it very much.
The answer to the riddle in the top left corner held me up for quite some time and I only solved it by finding a string of words and then seeing how it might serve as an answer, finally realizing there was a reference to children's literature.
I look at AB sometimes, though I never post there, and I agree with the comments made here. The self-satisfaction is not quite as bad as it used to be. Almost every week someone would say: "I spotted the theme straight away and it's a favourite one of mine", but that has been less the case over time.
