In the last couple of days, there has been a few cosmetic changes to this site, namely a new theme (TwentyTwelve), along with customized CSS (Wikipedia) for correcting some annoyances and making some other style tweaks. Additionally, there will probably be some more CSS tweaking in the following days.
