I don't agree that the growing use of homophones is efficient (your - you're, defunked - defunct, etc.). I think it is the manifestation of linguistic ignorance and it troubles me. I believe that the linguistic and the conceptual are linked and that a diminution of the former leads to the diminution of the latter.
