OMG, you guys. Check out this total burn by the CMOS:
etc. This is the abbreviated form of et cetera ("and other things"); it should never be used in reference to people. Etc. implies that a list of things is too extensive to recite (and indeed it should be used only after at least two items, never just one). But often writers seem to run out of thoughts and tack on etc. for no real purpose.
Yeah, writers. You just got burned by the Chicago Manual of Style.
