AdSense picks the advertisements for my blog.
At the moment, there are ads for psychics on the left side of my blog. I don't believe in psychics or divination or fortunetelling at all but they are one type of ad you can't block. (and this post will probably engender more of them because the word "psychic" is in it -- blargel)
Ironically, on the right side of my blog, there are ads for books about Christian missionary heros and overcoming temptation. A strange juxtaposition.
I think I will take the ads off my blog. They aren't really earning me anything anyways and maybe people are sick of the numbers of ads they encounter everyday.
That means I will need to change the look of my blog.
