I feel like a lot of these issues deal with super minor typographical thoughts, so feel free to discard any comment/thought/observation.

There are a handful of places where the notation $\text{span}\ V$ is used rather than $\text{span}(V)$; I'm sure that's an easy fix, so I'm going to stop adding those comments.
