Two One very minor bugs in the UI for the moderator history listing on Math.SE (though I wonder if the same problem happens on other SEs).
As you can see, one of my fellow moderator's name is a bit on the long side, and his diamond mark became a wedge.(Edit: as Cody indicated in the comments, this is by design.)- This is the listing for activities for the day. There's no way I could post 389 comments on Meta in one day. I don't even know if Jon Skeet can do that. Those numbers on the last two columns appear to be life-time totals, judging from the fact that changing the display to "month", "quarter", and "all" does not affect the number displayed in those columns.
