Sometimes, there are questions that let you really curious about what will be the final solution (if there is finally a solution). And I wonder if there is any way to subscribe to that question, and receive updates as they happen.

You can favorite questions (star icon under voting arrows) and there is your favorites tab in your profile.
Though I don't think there is proactive option to have it email you or something, so you will probably just have to check it in profile now and then. It will track and show if any changes happened since last time you viewed the thread.
