At AVC, they include multiple css to make to make it mobile friendly. <link rel="stylesheet" href="/a_vc/style.css" type="text/css" media="screen" /> <link rel="stylesheet" href="/a_vc/touch.css" type="text/css" media="only screen and (max-device-width: 480px)" /> <link rel="stylesheet" href="/a_vc/touch.css" type="text/css" media="only screen and (min-device-width: 481px) and (max-device-width: 1024px)" /> <link rel="stylesheet" href="/a_vc/print.css" type="text/css" media="print" />
Nothing of this sort with posterous.com... I could be wrong here. Not sure if anyone else has got experience making their website mobile friendly, if so, please share.
