Why doesn't Patrick Rothfuss have his own thread?

I'll quote something another moderator posted regarding an enquiry about why a different author (John Scalzi) didn't have a subforum here:
Unfortunately, it's not practical to start subforums just because writers are popular or highly regarded. There needs to be sufficient interest here at the Chrons. Unless the writer is a member here (and is therefore assumed to generate and maintain interest in his or her own books), the current measure of sufficient interest is 10 threads devoted to that author, at least one or two have to be currently active.

So, look around and see if there are any threads, start one or two about some of his works that you like, and see if you can generate enough interest.
