Or at the very least citations should include a specific revision. When citing from a journal or a book, you always include the revision image (publisher, edition, year-published). The idea is to allow the reader to check up on your sources rather than fulfilling some arbitrary administrative requirement (homework). As I mentioned above, that points out the teachers' rather than the students' competence.

We could compile together the list of suggestions generated here in this discussion, open up a new Wikipedia page on how to actually cite and use Wikipedia. Then get the word out.
