1. This comment thread shows comments in random order, so you're not seeing the more upvoted questions bubble to the top the way they usually would, which prevents winner-takes-all feedback loops in the voting.

2. People browsing through the thread may upvote good questions, but currently the scores are hidden in order to avoid bias.

3. Once the thread has been up for a while, the people doing the AMA can just re-sort to show the highest-voted comments first, which will give a good starting point for which questions to answer.
