There has been a lot of discussion of the importance of open access on Twitter. I am 100% in favor of open access (I do wish it was less expensive), but I also think that sometimes people lose sight of other important issues for junior scientists that go beyond open access. Dr. Isis has a great example of this on her blog.
A really nice post that made the rounds in the economics blogosphere talking about the use of mathematics in econ. This seems like a pretty relevant quote, “Instead, it was just some random thing that someone made up and wrote down because A) it was tractable to work with, and B) it sounded plausible enough so that most other economists who looked at it tended not to make too much of a fuss.”
