I disagree, as a rubyist I find it really useful that everyone uses underscores. Language-wide style conventions make it easier to remember methods and classes since remembering a method like each_with_index as a phrase is easy, attaching a piece of useless data unrelated to what it does like Camel Case vs underscore is harder.
