An Explanation of Blog Changes

I added some pay-for-clicks ads to my blog because, well, I am going to need money anywhere I can get it now that it looks like I am going to pay books and fees a couple times next year (aside from the bigger stuff).  The plus side is that I get to share some book recommendations with you through an Amazon widget!  But I still half-feel that I need to apologize for the extraneous content.  So take this as my apology.
