A few days ago, I noticed a change to the layout of profile pages on the site:
The blue box used to be higher up, with the elements up top further to the left. Unless I'm missing something, the current profile page has a bug that has broken the familiar layout.
Chrome 19 shows this bug, along with Firefox 12 and 13. Firefox 10 does not show the bug on this site, but does on some other SE sites.
