Because: * Google Docs is the best WYSIWYG on the internet; * blogging can be just about writing on a cool interface, without having to setup blog platforms AND go on their messy interface to write; * regular people can use this; * the written content stays on Google Drive, so you can delete your blog and keep everything without dealing with strange database backups; * almost-compatible with Jekyll-Octopress themes (some changes on the code have to be made, and for now only I can add themes to the pool of themes, but we will see what happens); * custom CSS (tomorrow javascript) files (automatically fetches from Google Drive) embedding.
