WordPress.com has made a big change in how they make their free themes available to the self hosted blogs. Earlier some of the themes were made available on the WordPress.org theme directory or via the author’s sites. But now WP.com is hosting all the free themes at their own site. Not only this, the themes you will download from WordPress.com can be updated via dashboard. So head now to their free themes library to download and use any of those themes on your self hosted blogs.
