The transcript of a great talk by Wilto, focusing on responsive images, inlining critical CSS, and webfont loading.
When we present users with a slow website, a loading spinner, laggy webfonts—or tell them outright that they‘re not using a website the right way—we’re breaking the fourth wall. We’ve gone so far as to invent an arbitary line between “webapp” and “website” so we could justify these decisions to ourselves: “well, but, this is a web app. It… it has… JSON. The people that can’t use the thing I built? They don’t get a say.”
We, as an industry, have nearly decided that we’re doing a great job as long as we don’t count the cases where we’re doing a terrible job.
