I almost applied to Berkeley Rhetoric, but at the last minute decided to do history instead. It seems like a great program/field ("field"), and I think a small part of me will always wonder if I would have gotten in, and what I would have done.
I think that these days, a person in almost any humanities/social science (or even science, if so inclined!) could incorporate the same methods and approaches into any project, and most do. It's still relevant and evolving, for sure, but I think the general ideas behind it have bled profusely into other disciplines.
