This is Jonathan Franzen. This isn't a Thumbs-Up photo, but I'm posting it anyway. He was this close to doing it but before I could take the picture he changed his mind. He said that he'd posed for a few photos in which the photographer had asked him to do something strange, and he regretted it afterwards. Jonathan Franzen is very cautious.
The Corrections is one of my favorite novels; I met him before it was published but he read from some of it. I think it took him like ten years to write.
