200 OK is the magic HTTP status. It's the one users should never see, since it essentially means 'all is well'.
In a sense, the web developer's job is to make 200 OK status codes happen. So that's why I chose 200ok for my domain name (the .au is me being parochial).
Anyway, this is the obligatory 'first post'; welcoming potential readers to the 200ok weblog. I hope you enjoy reading the site.
