Over at Blogger Buzz, Blogger has announced that there are now 77 special fonts available to use on your blog. You can see the selection at Google Fonts.
To try it out on your Blogspot blog, go into the Advanced tab of the Blogger Template Designer for your blog, select the type of text you’d like to change (Post Title, Blog Title, etc.) and click on any of the new Web Fonts for a preview. When you’re happy with your selection, click “Apply to Blog” and voila!
If you blog on a different platform, Google Fonts is available as a plugin, module or extension for WordPress, Drupal or Joomla respectively.
Have fun!
