When I view the front page right now in Safari, I see:
Notice that the question mark, which the poster properly placed at the end of the equation (see the question (before another edit removed the question mark) at https://mathoverflow.net/revisions/329925/2), appears at the end of the first line, mid-inequality. I think that this is probably a result of a relatively narrow window width (138 characters). I'm not sure what to say about this except that it's obviously (presumably?) not the way it should be rendering.
