Here's an interesting idea: utilize Gmail and it's gigabyte of storage as a blog platform. Some open-source software named Gallina can supposedly do this.
Gallina uses Gmail messages as blog entries, and the email service's message star to signify the publish status. Email replies to conversations are posted as comments to an entry. Because Gmail provides 1GB of email storage space for free, Hernandez' software makes that space available for the blog. --ZDNet
