Topic: What do you think about dedicated, commercial Rails Themes?

I developed a commercial Rails theme called {rails}strap. Its basically a Gem which saves precious developer time because you don't have to setup the Asset Pipeline and go trough heaps of JS and CSS files to change the asset paths etc. It also looks alot nicer than the standard Twitter Bootstrap design wink

Altough I didn't sell that much until now I can see that there is a little bit of demand here. On the other hand I know that Rails is choosen mostly because a generalized solution like Wordpress doesnt fit the requirements. Because I'm thinking about doing this with more themes I would like to have your insights on the issue. Do you think there is a demand for ready-made, commercial Rails Themes or not?
