I'm using Nikola to create this site. It's a static site and blog generator written in Python. It separates content from format by using themes which are packed with CSS and Javascript. It allows me to write content in simple markdown and then build and deploy the site in a couple of command-line commands.

• I can write everything offline.
• No horrible pseudo-wysiwyg editors with nasty rich-text controls and other crap embedded in Web pages and control panels.
• Not backed by and rendered from a database, so it's rendered fast.
• Backup of content is totally under my control
• Nikola's excellent templating system which makes it very easy for someone who can't see to create a blog and static pages that don't look like a dog's dinner.
