According to
https://www.mediawiki.org/wiki/Typography_refresh/Font_choice#Body_font_eva…
sans scores 0 out of 10 points for "readability,
neutrality, and "authority" (does the font look like it conveys reliable
information)." Apparently the font is not readable, neutral or authoritive
at all, and completely unsuitable for the website. If it is in fact almost
completely unreadable it seems reasonable to override it, even if it is
the
system default, but I have the feeling that there may
be some hyperbole in
that table. That said, with
https://bugzilla.wikimedia.org/show_bug.cgi?id=61470 it seems a terrible
idea to have Helvetica Neue in the font stack.
Really a 0? What would comic sans get?
