I believe I'm done tinkering. I have done my best to optimize for readability and clarity.
I've also stripped out links to Google to serve our past font and made everything OS-driven. For modern computers/OSes with modern screens, everything should look exceptionally clean and clear. And, going this route will give us the tiniest of performance boosts. I also have fixed a lot of minor issues I found in a QA pass across desktop and mobile. I was surprised by how many little issues I discovered, which I think are looking much better now.
I may do a little bit in the posting screen later this summer (I've never been a fan of the image attachment UI) but saving that for another day. Let me know if you think you've run across anything funky my changes may have caused that I didn't catch.
