This is the software publisher’s description.

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. Here are three key features that we are most excited about:

WYSIWYG Authoring. The first thing to notice about Writer is that it enables true WYSIWYG blog authoring. You can now author your post and know exactly what it will look like before you publish it. Writer knows the styles of your blog such as headings, fonts, colors, background images, paragraph spacing, margins and block quotes and enables you to edit your post using these styles.

Photo Publishing. Writer makes inserting, customizing, and uploading photos to your blog a snap. You can insert a photo into your post by browsing image thumbnails through the “Insert Picture” dialog or by copying and pasting from a web page.

Map Publishing. Whether you are blogging about a vacation or a political conflict, maps are a great help in engaging the imagination of your readers. You can do this using Writer's ability to insert a Windows Live Local map directly into a post.
