Do you know of any similar websites? I have a couple of questions that I would like to see answered. I emailed mr Munroe in the past but he never replied, I'm sure he has thousands of questions from readers to choose from.
https://waitbutwhy.com/ is pretty good, you need to set aside a decent chunk of time for each article typically.
/r/AskScience on Reddit is pretty great in getting your random questions answered - perhaps not in the same entertaining way, but there's definitely some smart people there.
