Blog Roll Switch

I have replaced educationrealist in my blog roll with West Hunter.  Educationrealist is a blog about teaching by a high school math teacher.  While I generally agree about the importance of innate cognitive ability (compared to other factors) in student achievement the fact is I am just not that interested in the details of teaching medium ability high school math classes.  West Hunter is a blog about human genetics (and other things) by two scientists (one of whom writes most of the posts) working in the field which I find more interesting.
