Also interesting is that if you have multiple blogs, like say this one and the family one, you can easily switch back and forth between the two which is kinda nice.
You can also edit recent posts that you've made via Windows Live Writer along with managing your blog settings. What is a bit strange is that while you can manage blog settings, and if you edit a recent post, it will go get the actual post from the blog, it doesn't give you a way to edit posts that you didn't make from the tool.
Something else that it should do for a real value add is give you the option to search from the tool to get a URL to hot-link. Instead of my having to go look up the URL for Windows Live, I should've been able to highlight "Windows Live" and pick an option to do a web search to find the URL for a hot-link. That would provide extra value with the power of a desktop app.
On the whole this little app seems like a nice addition.
