Excuse the pun in the title. BlogDesk is a desktop blogging tool (also known variously as an offline blog editor, desktop blog editor, etc.)
Instead of going online and using the web interface to write your blog post, BlogDesk allows you to compose your post on your computer (even when offline). LifeHacker compared a few other blogging tools.
More small businesses are now using blog as a as a channel to engage and communicate with customers. If you maintain a blog, BlogDesk and help you in several ways which I will outline in this post.
After using BlogDesk for more than a year, I can heartily recommend it!
