Reading

I like to think of it it with the question: what is to reading what a text-editor is to typing? Social features for sure. We could also experiment with crazy stuff like SYNTACTIC SPACING. Here's an illustration on a paragraph from Doug Englebart's Augmenting Human Intellect:

Do not read, as children do, to amuse yourself, or like the ambitious, for the purpose of instruction. No, read in order to live.

— Gustave Flaubert
