Take a look at Ramaze. It's my first choice for doing Ruby Web development and I've found it works really well for projects of any size. What I especially like is that I can start with a single-page static HTML "app" and evolve it out as needed, and refactoring or moving things about are never an issue. I don't worry about having to turn stuff off or tripping over someone else's conventions. (For the latter: I do not like the convention of grouping all models in folder, all views i another, and controllers off some place else. I prefer to treat related MVC components as a "tuple" and keep them together. This is how, for example, it's done with Monkeybars; I find it much more logically coherent, and this is how I organise my Ramaze projects.)
