Windows Live Writer is great when you are posting to multiple blogs too. You don't have to to each of the blog's admin panels. You simply use the dropdown to change which blog you're posting too. And if you're making similar posts to different blogs, you simply use the drop down to change blogs, the previous blog post is still there, you make your minor edits, and hit Publish, and it publishes the new modified post to the newly selected blog.

Can be a real time saver.
