Habermas for Nobel prize in Philosophy?

Professor Leiter on his blog has put a following hypothetical query to his readers:

"if there were a Nobel Prize in philosophy, who among living philosophers should get it and why? Feel free, of course, to nominate Charles Taylor! Some obvious figures from the post-War era--like Quine, Rawls, Sartre, and Foucault--are, alas, deceased."

I thought Habermasians can participate in the survey by nominating Habermas!
