Tildes UI design

Hey everyone,
I've seen a bunch of posts discussing the design of the site, and I was wondering if there are any other designers on here that would be interested in discussing the interface more precisely, and coming up with potential improvements. I wrote up a design audit and gave it to @Deimos last week, and I wanted to share it with everyone and generate some discussion about minutiae such as colors, placement and styles of buttons and links, etc. I feel like these are just as important as larger features that people are asking for (such as a markdown preview), and have the added benefit of being very fast to iterate on.
