Personally, I prefer indefinite articles for third person when possible, but you should talk to folks fluent in your target languages for clarification. For example, when we're talking in French, I don't mind folks (especially students and non-native speakers like myself) confusing on/il/elle. Il faut imaginer and On faut imaginer are only very subtly different and not enough to bother this French speaker. That said, if you're posting to someplace that deals with regular recurrences of Eternal September, you're better off being cautious. A lot of the 25-35 year old "digital native" crowd has been seriously burned by WELL leaks and the like.
