You're about to start a new Rails project. Do you type rails <project name>? No, "Stop using the rails command", says Josh Susser. If you create a dummy / default Rails project that's set up just the way you like it with plugins, your own extensions, and all those carefully defined svn:ignore flags, you can just create a new Rails project with a simple svn copy. So simple, but I've totally missed this idea, and it's a real timesaver.
