Cool. Radio Userland had support for blogging from Word back in 2001. Just had fewer features and didn't have the backing of a billion dollar company. The revolution continues. In the future every tool will have blogging (and VoIP like Skype) built in where it makes sense.
Now you can use Blogger right within Microsoft® Word. Just download and install the Blogger for Word add-in and a Blogger toolbar will be added to Word allowing you to: Publish to your blog, Save drafts, Edit Posts
