I must say that Windows Live Writer is very nice. One thing I really like is the context sensitive sidebar. Normally, as you type, it is in insert mode (insert link, insert tags, etc). If you click on an image, it switches to image mode and lets you perform functions related to image.
Here are some of the features.
* Edit your entries using your blog's standard headings, fonts, and colors.
* Switch between HTML source-code editing, WYSIWYG ("What you see is what you get," which means that you can see the formatted page, but not the HTML code that creates the formatting.) editing, and web preview modes.
* Preview your post before you upload it.
* Compose posts offline.
* Insert photos, maps, and other graphics.
* Resize graphics, and add borders or other effects. Cool things like watermarks (see the image above) and some minor photo editing.
* Create thumbnail image links to larger graphics.
* Upload photos directly to blog providers who support the new Media Object API (An XML-based application programming interface that provides upload information about images, movies, songs, or other types of media when you upload media from your computer to your blog.) or to an FTP server.
* Compose posts for Windows Live Spaces as well as Blogger, LiveJournal, TypePad, WordPress, and many other services.
* Works with Really Simple Discoverability (RSD) (An XML format that makes it simple to set up editing or blogging software to use with blogging sites.) , the Metaweblog API (An XML-based application programming interface that allows other applications to interact with a blog site.) , and the Movable Type API (An XML-based application programming interface that extends the Metaweblog API.) .
If you are a blogger, give it a try!
