Dan Cederholm (Designer) and Dan Benjamin (Developer) have sold their excellent web collaboration project Cork'd, which was made out of a passion and interest in wine. Cork’d is a free service for reviewing, sharing and discovering wine. It was made using Ruby on Rails and Dan Cederholm has pointed out a few times his positive experience using Rails as a web designer, comparing it to sculpting, which has been also my own experience working Ruby on Rails here.

Cork'd was made in the spare time of the designer and developer and has a community of over 20,000 users today. I don't have any idea how it scores on revenue but it is impressive all the same. Shows what can be done when a project is your own, has a very clearly defined audience, you have the tools and ability to make it, and you are passionate about it.
