There's nothing "co" about this "coed"

Bill Walsh points out at Blogslot that "coeds" seems to be making a comeback.

I've used the word as a throwaway inclusion in copy-editing tests, including my contribution to this year's test for Washington Post copy-editing internships. This time it wasn't such a throwaway, as almost all the applicants let it stand. Only one flagged it with the red-pencil equivalent of the gasp it deserved. When I saw these results, a day after hearing a television reference to "coeds" that further eroded the original meaning by referring to students of both sexes, I started to think the word might be making a comeback.

Help him (and humanity) by making sure this doesn't happen in the copy you edit.
