Re: Dinosaur endothermy: bone growth rings in found in mammals too

[Mike Taylor <mike@indexdata.com>]

I realised I just crossed a Rubicon. As I read the title I was
somewhat interested, then saw where it's published and found myself
thinking, "Oh, it's only in Nature, I thought that sounded good enough
for PLoS".

I realise that people who have to worry about impact factors for their
jobs aren't in a position to concur (yet), but I've reached the point
now where my honest feeling is that a paper in a PLoS journal is a
bigger deal, and more to be desired, than one in Nature.
