There has been a new theme added to WordPress.com, and this time it is a beautiful dark theme called ChaosTheory.
Interestingly enough, it was designed exclusively for WordPress.com.
From the blog post:
It features an unusual single-column layout with two widget sidebars at the bottom, and a page navigation menu at the top. You’ll find it listed on Page 1 of your dashboard’s Presentation tab.
This is definitely not one of those sleazy link-whoring tactics, as the creator of the theme hasn’t even been mentioned.
