I used to do a simple rails site for anything I put on the web. I switch to html based site for things that I wasn't updating much. The reason was to save on memory usage on my vps. For a site of any complexity, I would use a cms, home-brewed or open-sourced though. Removing the database layer is always a nice option, but if you plan to have any sort of interactivity, straight html might be a pain.
