Has anybody actually studied the effect on actual users of removing schemes like [[Wikipedia:Pronunciation respelling key]] in favor of IPA?
It's obvious that having IPA pronunciations advances our mission for a certain highly educated segment of user. But for the rest of our readers, the answer seems to be, "Well, you should learn IPA."
Although it's probably true that they *should* learn it; the question I think we should answer is whether they *are* learning it. If not, then stripping a key they can read in favor of one they can't would move us away from our vision, which is people sharing freely in knowledge.
