> One problem I encounter with math wiki is that I almost need to know what it is before reading to understand the wiki page.

Case in point, nLab: https://ncatlab.org/nlab/show/HomePage

For instance, https://ncatlab.org/nlab/show/homotopy+type+theory

Although this is partly inevitable because the content is really abstract, I know there are more approachable ways to define “monad” than https://ncatlab.org/nlab/show/monad
