Several issues have come up related to appropriate terminology. Rather than discuss these each time they come up, I suggest using this question as a catch-all place for noting the acceptable terminology to use. This will make it easy to link to when editing.
New suggestions are welcome here, but if you have objection or what to see further discussion of this issue other than the ones referenced, please open a new meta thread and link to it in a comment on the relevant point. This thread is not a poll! It is a convenient reference to link when commenting or editing answers. We will all keep it up to date with the general consensus from individual threads.
