WYSIWYG
Because programmers are gatekeepers to web technology, and because programmers are influenced by Hacker Culture, the biases’ of Hacker Culture have an impact outside of this subculture. The world of programming is responsible for its own tools, and contemporary web-sites are built by programmers upon Open Source libraries developed by other programmers. Shaped by the culture of Unix and plain-text, and by the practice of programming, WYSIWYG interfaces are not interesting to most Open Source developers. Following the mantra to ‘scratch one’s own itch’, developers work on the interfaces that interest them.
