Ruby on Rails Hosting
sant0sk1: Heroku FTW. (http://heroku.com/)Especially since you'd be supporting a YC startup and they are great for beginners because of their pretty powerful in-browser editor. You don't even need your own dev environnment if you don't want.Also the service is free during beta. Not sure if the beta is still closed, but ping me if it is as I'm sure I have some invites available.
