Yup. Further, the goal of the MIT and GPL licenses are very different, as far as I understand it (and I am not an expert here, so could be totally wrong!) but from my limited understanding, the MIT license is good for people who want their code to be used by as many as possible. The GPL license is good for people who have a real desire to contribute to an open source world, while simultaneously and explicitly trying to not give the benefits of their contribution to closed-source efforts.
