I have the feeling that a lot of people will not get their questions answered. But lets just try and complain later. 
I agree with @freibadschwimmer, the evening is the right time to do this.
Here is a link to @anon48893843 biography. Thank you for being the first!
Although I think he’s not the right person for this first AMA (he is currently “just” the face of support answering unanswered tickets that show up in the forum as unanswered … often late at night! Thanks for that, btw.). But I’m not sure if he can tell us a lot about the root cause of the support problems? Is this still his expertise? But I guess we will find out. I would have expected the Technical Support Representative to answer the first AMA. But I guess it’s a PR thing, at least it’s someone who is already known in the forum. And he also wrote a blog post about QA related stuff a while ago so he will know about QA. 
“Finally, based on the experience of the Fairphone 1, we now have access to our own repair statistics which allow us to make more accurate assumptions and estimates.”
One AMA related question: Will “upper management” - people with “Chief/Senior” in the job description get involved in later AMAs as well? They don’t show up here in the Forum that … often. I also would like to discuss much more often with the value/supply chain crew.
Update: Blog entries written by @anon48893843. Maybe this will help asking good questions.
