I dunno. I say lots of things to people's faces. Sometimes I say it to someone else first though, just to work it out, or maybe I say it to someone else after, because they didn't listen. Or maybe I said it to them politely and then to someone else less politely.

Of course, for me this is mostly about RL behavior. I talk negatively about other people in my journal very very rarely, and when I do I never mention names.
