Windows Live Writer is a desktop application that makes it easier to compose compelling blog posts using Windows Live Spaces or your current blog service. Blogging has turned the web into a two-way communications medium. Our goal in creating Writer is to help make blogging more powerful, intuitive, and fun for everyone.
Writer has lots of features which we hope make for a better blogging experience. Some of the ones we are most excited about include WYSIWYG authoring, photo publishing, map publishing, Writer SDK and compatibility.
