I think you fellow solvers will find this talk interesting. There's a few minutes of the usual who am I and what is AoC but there's some good stuff about growing pains, the puzzle design process and why he likes to throw in a hard puzzle in an early day.

edit: bah, I see it was already posted - the Lemmy search doesn't seem to find it unless you limit the search to URL...
