TechCrunch reports that the fancy-pants Four Barrel Coffee--which doesn't deign to offer Wifi--recently posted a list of rules for patrons. It was promptly posted on Instagram. The luddite baristas then posted an updated list of rules, adding, “No posting this on Instagram, you hipster.” The sign was, once again, promptly posted on Instagram.

If someone posts a screenshot of the TechCrunch post on Instagram, then the entire Internet will disappear in a cloud of self-referential smoke.
