Thanks for posting this. We are in the process of building a notifications management page so you can unfollow specific questions. In the mean time, you can unfollow specific questions by visiting the page where the question is posted and clicking the 'unfollow' button in the blue 'Followers' box in the right column. There should be a direct link to the question in the emails you are receiving. If you don't see the 'Unfollow' button, that means you are logged out and will need to log in. Once you log in, the button should appear. I know it's not perfect, but hopefully that will suffice for now...
