Lipogram

Lipogram, a literary piece in which one letter of the alphabet is intentionally avoided. The ultimate challenge is skipping over common letters — like Ernest Vincent Wright’s novel Gadsby, which has 50,000 words but not a single ‘E’ to be found.

Elite projection

Elite projection is the belief, among relatively fortunate and influential people, that what those people find convenient or attractive is good for the society as a whole.  Once you learn to recognize this simple mistake, you see it everywhere.  It is perhaps the single most comprehensive barrier to prosperous, just, and liberating cities. -Jarrett Walker, Human Transit
