I put them there mainly as a whim since a) It's free and b) someday when I'm destitute but read by millions, these ads will put food on the table. Admittedly, I am not giving up my day job banking that "b" will happen. However, my wife just informed me that she just noticed the ads them and has been clicking on them all day. :D I let her know that Google probably tracks cookies so that clicking on them repeatedly won't make us rich, but I appreciate the intent. She's always looking out for me. A truly lovely person.
