WordPress.com users rejoice, the WordPress team has added a new and welcomed feature - custom CSS. Until now, you had to stick with the limited customization that came with the stock themes. By purchasing the custom CSS upgrade in your WordPress.com blog's admin panel for 15 USD, you have the ability to edit the CSS on your blog for one year. When the year is over you will have to purchase that upgrade again if you wish to make any further changes. I think this is a great way to mature WordPress.com's business model while letting users rake up on the feature-set.
