The new default theme for WordPress 3.6, titled Twenty Thirteen, is making progress. This year’s default theme is overseen by Matt Mullenweg, and built by Joen Asmussen, Konstantin Obenland, and Lance Willett.
The goal for Twenty Thirteen is to offer “a focus on blogging, and great support for post formats (which are getting attention on the backend in 3.6 as well).”
If you’d like to see the theme in action, a demo site is available. One thing you’ll notice immediately is that the strong emphasis on whitespace, which has become commonplace in the default themes, is long-gone. Twenty Thirteen is making very bold use of its colors, offering a different color for each post format. The theme also lacks a sidebar by default. It’s designed to focus on blogging after all, so the designers prefer that you leave your widgets to the footer area, but it still does support a sidebar widget area if you really want to put something there.
This theme won’t be for everyone, and really no default theme should. Default themes should showcase the strength of each release’s new features and inspire customization. If you aren’t a fan of Twenty Thirteen, don’t worry, there are still over 1,600 themes to choose from, including Twenty Twelve.
