Subject to addition.

“After the jump”
A superflous, stupid call to click read more, on sites that require it.

When we need to hit [cmd]+[-] five times to read more than a paragraph.
For those who didn’t want the default Times font, but still lack imagination.
The meatstack/hamburger icon
Inscrutable, pointless navigation obfuscation.
Helvetica Neue Ultralight on non–retina screens
There’s a reason we didn’t do this on screens before.
