They were doing some system maintenance yesterday. May be a result.
You didn't by any chance bump up the default font size to Large Fonts during the maintenence, did you? I haven't done anything to change my settings, but today everything looks bigger on this site, and easier to read, BTW.
*Never mind, I see what happened - I accidentally hit the CTRL Key and +, which activated the Zoom on Explorer8, so I was viewing at 125% of normal size. It is easier to read, though.
