NewsGator just released a production version of their Movable Type posting plug-in.  It joins a bunch of other posting plug-ins including TypePad and Blogger.  With this, you can post directly to your blog from within Outlook using all the normal Outlook editing features such as bold, italics, and colors.  

Lists are easy also:

• Just like sending emails.
• Formatting is automatic.
• Bullets are pretty.

Using the plug-in, posting is as simple as sending an email, which is especially convenient if you live in Outlook like I do.
