I’ve just upgraded to WordPress 3.8, with some minor tweaks to make it my own. I like the aesthetics of this new release, Lato works well on several resolutions. Exo would be my second choice. Choosing a typeface is one of the things I need to avoid, I just can’t seem to be perfectly happy with any free ones and buying one for such a very casual blog would be senseless.
I’m actually not sure how much longer I’ll keep running this blog on WordPress, a database is just not needed to support a simple blog. Perhaps they’d fork it eventually, or I’ll just move to a markdown powered software. We’ll see.
