Today, Mark Mayo resigned as a moderator, claiming to be burned out on multiple fronts. I'd like to thank him for his service to the site as a moderator.
Mark was one of the site's initial beta moderators, appointed shortly after the site went into public beta, and was elected back into the moderator position in the 2016 election. He's also been the site's highest-reputation user for many years, contributing nearly 2,000 answers over the course of this site. In addition to that, he's won many site competitions: the April 2015 Answerathon and at least four photo competitions, not to mention others.
My first interaction with him (which I can recall) was when he put a bounty on one of my questions that wasn't receiving good answers. All my later interactions with him have been nothing but positive.
Please join me in thanking Mark Mayo for his service to the site as a moderator.
