The font seems OK to me. It just makes 1s look a bit odd. But then maybe that's because I'm so used to stupid fonts that make it impossible to tell the difference.
On the other hand, we do seem to have a few representatives of the font taliban on here. Which is a subject I'm mostly ignorant of and have no strong feelings about. I should care, given my poor eyesight.
I did actually complain last week, when filling out an accessibility survey for the Guardian. Who decided, in their wisdom, to consult on accessibility of their website in light grey 8pt Times New Roman. So I can easily read their page, but was struggling to proof my own submission... I thought serif fonts were out of favour for a reason. And it's particularly odd, as the rest of the site is in a nice, clean sans serif.
