I thought Noah Smith's post on why we should teach intro micro before intro macro was very good. I agree with Noah: even though macro is much more glamorous, micro is just as useful and important, and we are more confident that micro works. (Read his post for the full story.)
I want to add a couple of points in support of Noah, then talk about what I think is a bigger issue: the splitting of micro and macro into two separate half courses. I'm against splittism, but it's getting harder and harder to fight off the separatist forces.
