You can now read and post to WordPress.com blogs using Tweetie2, a third-party iPhone Twitter application.
This is cool because it’s like having mobile Twitter but for blogs. You can read and post to your blog and also read other WordPress.com blogs.
WordPress finally added an Email Subscription feature to its WordPress.com blogs. This is a great new feature because it is much easier than adding in a third-party email subscription option like Feedburner.
