As I predicted a little while ago, this manuscript has attracted a lot of discussion:
It seems that ESD is turning into a bit of a hotbed of debate with plenty of controversial papers. It's interesting to see the review process out in the open, especially in these sort of disputed cases. Too late for anyone to add any more comments now. Unfortunately the second phase of revision and re-review will be hidden from view (this being the standard policy of these journals - I'm not sure why really). So if any commenters have anything else to add, they can do it here instead!
