My Stack Overflow Careers profile includes links to a couple of my projects, and their websites contain markup like
<link rel="shortcut icon" sizes="16x16 32x32" type="image/png" href="/myproject/favicon.png"/>
Instead of displaying the favicons, though, SO Careers displays a placeholder (a white box with a gray border). I think everything here is valid HTML5, except for the inclusion of
shortcut in the
rel attribute (which is necessary for IE)… am I doing something wrong, or is SOC parsing my site incorrectly?
