There's not really much curious conversation when they happen, and not really a huge chance of it, either. As an example, the announcement of sama taking over was a hundred and fifty comments of almost exclusively "Congratulations!"
They're posts that are almost exclusively doomed, either to incurious compliments, insults, or needless pessimism; what questions that are asked usually don't get answered, so there wouldn't really be a loss in it anyway.
