I noticed on MathOverflow (specifically, see the first two revisions of http://mathoverflow.net/revisions/87249/list) that MathJax makes excessive space next to the AMS symbols `\ulcorner` and `\urcorner` (and presumably `\llcorner`, `\lrcorner`). It seems as if these symbols were treated as binary operations by MathJax, whereas in the amssymb package proper, `\ulcorner` and `\llcorner` are left delimiters, and `\urcorner` and `\lrcorner` are right delimiters. (Indeed, one can get the correct spacing in MathJax by writing `\left\ulcorner ... \right\urcorner`.)
