When using OpenSuSE 11.3, the font for titles, votes and views counts has a very odd-looking character "2". It has an unusual serif-like crossing in the bottom part (sorry, I don't know the exact terminology in typography for calling that line).
It might be just me, but it took me a while to figure out that it is a 2 and not a 4 with a curved upper part. Besides, that font looks horribly baroque and unreadable to my eye.
The offending typeface seems to be OpenSuSE's version of Palatino.
