I used to use Windows Live Writer for my blogs (yes, plural. It can connect to several major blog platform) and I think it was the best desktop application for bloggers, but unfortunately, Microsoft stopped the development in 2012 and I stopped using it too. The good news is that Microsoft recently started an open source fork of Windows Live Writer called Open Live Writer and released the initial public version just a few days ago. I am going to give it a try to see how it works.
