I thought specifying a fallback font does that. Of course, problem is that many websites try to avoid the dreaded FOUT, and end up hiding text, or even the whole site, until fonts are loaded.
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.
I regularly test my websites with various tc settings, including traffic shaping, packet loss, line outages etc. Lots of manual work, but it really helps to see which parts of your API can be traffic-optimized.
