If you are a blogger and use Windows and Movable Type, b2, BigBlogTool, Blogalia, Blogger Pro, BlogWorks, or Nucleus then you might be interested in w. Bloggar, otherwise skip this post.
This applications is a regular windows application that is very easy to setup for a novice and allows you to easily format your posts. The newest version 3.01 that just came out now allows you to preview posts using a specified CSS style sheet and also adds support for MT extended comments. Spellchecking is also included. Once your post is ready it will publish your post with a push of a button.
If you are so inclined you can even have the name of the current song or video playing in Windows Media Player 9 added to your post. But best of all this application is free.
