There are many, many other things I am busy picking nits with. Though the problem with picking nits is that your are picking nits with someone. And that someone might be asked to review your paper. So it is best at this stage of the game to work on bringing ideas together without doing too much criticism, so that everyone just sort of nods their heads without needing to get defensive.
I have never been a nit picker. Mama Claghorn didn't raise me like that.
