Live Writer

I first heard about this through our blog ring - GirlTalk Bloggers. It's supposed to be cool and handy. Anyhow, I am using Live Writer

Here's an overview:

Windows Live Writer is a desktop application that makes it easy to publish rich content to your blog.

Publish to most major blog services
Including Windows Live Spaces, SharePoint, Wordpress, Blogger and many others. Don't have a blog yet? Writer will help you set one up!

Create a compelling blog easily
Insert photos and videos, maps, tags and lots of other cool content, all in a snap. Powerful editing features include tables, spell checker, and quick hyperlinks.

Preview before you post
Writer shows you what your blog entry will look like before you post it, using your blog's templates and formatting.

Compose your entries offline
Publish them later, when you get back online.

Try it. It's very useful. Whenever you don't have Internet connection, you can just compose your entries and publish them whenever you are online next.
