It’d be here on the forum.
I mean, it’s “ask me anything”, so if someone wants to know what Kai Greene’s favorite pizza topping is (please don’t say grapefruit), that’s on the question-asker. If someone wants to ask a WSM finalist for overhead press tips, that’s a different story.
Also worth noting, it’s not “I’ll Answer Anything”, so asking an active competitor in a drug-tested sport about their cycle probably wouldn’t yield much info. A retired competitor though, hmmm.
