I've just noticed that the username and reputation you see on the question lists are now very close. I presume this is a side-effect of the new-nav because it only happens on MSO, SO, and MSE (here) (and not on other sites, such as SR):
It doesn't look right. There must have been a reason for there to be a space before. Why remove it? It looked better before:
We could either add a
margin-left on the
reputation-score class, or just add a
between the username and rep score.
