If uses typing the all caps verison of AJAX by accident really is a problem then we should keep the disambig at the top of the page though I dislike it as it s messy and and we d only be doing it to help users who have made what amounts to a typo It s certainly preferable to redirecting AJAX to the disambig see the relevant alk page for the reasoning on that But again I have real trouble beleiving that this is really all that much of a problem or that it happens very often
