Perhaps I'm a bit dense today, but why are you unable to link to descriptions of one or more of these better approaches? Many people would find the information useful and interesting.
Sorry, I fully intended to publish a description, but it turns out at least two of them are the subject of pending patent apps that haven't been published yet, so I can't.
In any case, do note there are a wide variety of wilson variants or alternatives that may be applicable to various situations (agresti-coull, etc), as well as jeffrey's prior bayesian intervals.
