I was just thinking about the AMA idea and recalled the Facebook chat @paulakreuzer and I did for T-Mobila Austria (Forum link). We were 2 “experts” and two women from the T-Mobile social media team, and it was hard to keep the overview and answer to all questions. And that’s with Facebook’s comment system being slightly better organized than Discourse’s (answers to a question appear directly below the question, no matter when they were asked).
So I have the feeling that Michiel will have a very hard time during the two hours. I’m suggesting a moderator, who deletes questions that don’t follow the rules (questions limit exceeded, has been asked before, etc -> rules would have to be agreed on first).
