The fonts are listed in alphabetical order.

But still, as stated in the article:

"It can be a little difficult to distinguish between uppercase i / lowercase L and nested single/double quotes but that can be said of many proportional fonts."

For source code editing, I'll stick to a monospaced font myself.

Agreed. If a new person starts working with me and they are not using a fixed width font, I immediately question their sanity and their skills.
