Fully agreed with your reason for leaving, but I'll throw in: it's absolutely terrible at showing time relevant information, seemingly on the theory that someone will dedup and edit every question and answer as it becomes history rather than helpful.

That became more and more clear as the site and content aged, and afaict they have done absolutely nothing to address it. So after a few years the site had good information... but often only if you had accidentally time traveled.

I had FAR too many cases where the correct answer now was much further down the page, and the highest rated (and correct at the time) answer was causing damage, and editing it to fix that would often be undone unless it was super obvious (if I even could). It shifted the site from "the most useful" to "everything still needs to be double checked off-site" and at that point any web search is roughly equivalent. And when it's not a destination for answers, it's not a destination for questions (or moderation) either.
