The latter are the worst of the bunch. Same goes for those fucktards who make their site load (i.e. remove the display:none on the content) on loading/error event (timeout etc) of the social media plugins. Oh, and of course no images and no nothing has been loaded... so ANOTHER time pressing ESC and hope that I finally will get some text.
Please, developers out there: test your websites on REAL mobile devices WITHOUT LTE/3G/UMTS. You WILL be surprised how fucking awful your site is on a low-bandwidth link.
