So I suspect it could actually be because of tab width varying in browsers (and custom settings). MotD used tabs for formatting, and I kept most of them to make my life simple.
Let me know the below one's properly formatted (it's all spaces- thanks Sublime):

(none of the data above is updated since MotD's initial post)
If the above stuff works for everyone, then I guess that means we shouldn't use tabs w/in code tags and expect the formatting to work perfectly across browsers.
Also, MotD's looks okay for me now too. It still has tabs, though, so maybe it was something else?
