You can use semantically meaningful class names and use the mixins from the Bootstrap source. Even though it's probably common practice and great for you know, bootstrapping, I don't think it's good for maintainability to leave the column classes in the markup. In a large, modular, front-end heavy project, proper separation of content, presentation, and other cross-cutting concerns really pays.
