Yeah. I also don’t want to be too negative, but I skimmed through the posts so far, and it seems like we don’t actually have much graphics or linear algebra yet. Instead, we have a bunch of wordy prose preparing us to someday get to the graphical linear algebra.

To the author: you might want to lead off with something a bit more substantive, or many readers are going to get bored and leave before you ever get to teach them anything.
