See http://news.ycombinator.com/item?id=4102598 (posted a little later than your comment) -- though I'm not sure anigbrowl is a regular moderator, he just mentions that he sometimes does change titles.

That's all I see, though -- and I agree, I was expecting to see a conversation that doesn't seem to be happening.

Well, hopefully the mods are listening and will be more cautious in their future edits....
