I think I have it pretty much where I want it at the moment, though I might do a little bit of further tweaking around the edges.
For those who are curious, the design is WordPress’ “Twenty Thirteen” theme, lightly tweaked via basic personalization (colors, images) and with a little CSS work to shrink the headlines down from their previously somewhat obnoxious size and to bump up the size of the main body text. Also, if your computer has the font Cambria in it anywhere, you’ll see the body text in it; otherwise it should be some sort of san serif.
Generally speaking, I like the new look. It feels a little more open and airy to me than the previous iteration of the site, and I suspect the bumped up typeface of the body text means it’s easier to read on retina-level tablets and laptops (also, for those machines, the sidebar automatically slides down underneath when your tablet is in portrait mode/your browser window is sized smallishly). In all, it brings the site up to, well, 2013, without making it overly complicated. It’s mostly the same, in fact; just a little bit prettier.
