What *is* our convention on BC / BCE and AD / CE?
On the en: wiki, the year, century, etc pages are called "BC", but I think a majority of articles use "BCE". I bumped into an article specifically about the naming system, which states that "BCE" and "CE" are now preferred, in general.
perhaps we should take our own advice?
I think we should give preference to the BC/AD system. Before I found Wikipedia, I had never heard of the other convention, and I think BC/AD is still the most used and best known system - the best reason for preferring it over the other. However, that should be for the article titles, I think we should be free to use it in text if somebody wants to, just like we don't prefer US English over British.
