Speaking strictly for myself, but as someone who spends about half his professional day writing Clojure: :use is dead, long live :require.
I've found using ":require [foo :refer :all]" rather than ":use foo" has lead to cleaner, more consistent ns statements in my own code, and I've made it a policy to convert old :use statements to ":refer :all" whenever possible.
