This is really cool.

Windows Live writer is a free tool from Microsoft that lets you post entries to your blog without having to log in to your blog provider website. It works more like Microsoft Word, with spell check as you type, easy formatting, and very easy insertion of pictures and tables. You can also put these cool drop shadows on your images!

If you're a blogger, give it a shot. It is also available with the latest version of Windows Live Messenger. Works with Google Blogger too!
