I've noticed that on the SO badge pages ("Recently awarded to") where moderators are among the winners, there's a slight mark-up issue whereby moderators aren't lined up properly (don't adhere to the same spacing as everyone else).
The moderator diamond seems to be the same height as the text, and the amount of badges/length of name doesn't seem to be part of the issue.
See screenshots below, examples from the Archaeologist badge page :

If it's relevant I'm on Firefox 18.0.1, but it's the same in Chrome 24.0.1312.56.
