You malign ad hoc pronunciation schemes, but they do have *some* redeeming value. You can use a single ad-hoc system to represent different dialects more easily than you can use IPA for the same purpose, since users will read their own dialect into the pronunciation guide for the ad-hoc system. Still, I can't imagine making up an ad-hoc scheme for wikipedia; IPA is probably best for us.
I agree with this criticism of IPA -- how can IPA even be remotely useful for us, given that there is no one correct phoneme mapping for nearly *any* word in the English language? Are we going to have dozens of different IPA entries for each word, representing the full range of pronunciation in the English of England (including many dialects), Scotland, Wales, Ireland, Australia, South Africa, India, the United States (including many dialects), etc.? And how about for the range of pronunciation of Chinese words within different parts of China, or countries outside China that also have significant Chinese-speaking populations? The whole thing just seems pretty useless.
