Email is actually a perfectly valid web publishing protocol. We've done quite a lot of systems where clients can publish news items by just mailing them to a certain mailbox.

And http://www.deathmonkey.org/ was completely produced by sending emails from (old, pre-iPhone) smartphones on the road.

Ditto. I update my blog via email.

I love posterous for this reason. I find email is a natural interface for a lot of things and only wish I could do more just through email (like, I dunno, email social network interface perhaps?)
