While reading through various questions, I noticed that while in code, tags (e.g.,
iIl1) are pretty easy to distinguish; in the standard font for questions, they are not (YMMV, but for all environments I have seen, they are not):
Of course not everyone has all fonts, but I was wondering if the CSS could be a better list, listing less ambiguous fonts earlier? Or maybe more fonts to increase the chances of people hitting a better, readable one? Currently the list is (at least displayed here):
Arial, Liberation Sans, DejaVu Sans, sans-serif
It seems that this is done on math.se and electronics.se at least (Georgia, "Times New Roman", Times, serif), although I have no idea if that's for a reason, or some default setting that SO is deviating from. Or does SO maybe have a guideline somewhere behind the font decision that I overlooked?
The core of the question: do we need to "try harder" to get less ambiguous fonts (mostly for iIl1, but maybe for others too) used for normal question text (probably by choosing a serif font like math.se), or are there other, probably more important reasons to use/keep the current font?
