Topic Follow Count

Be able to see how many people follow your topics, maybe a button, or a number at the top of a topic near the title? I think it would be cool to see who follows your topics, or at least see a number of how many people think it's a great topic. I think a huge part of the sites is being able to have others appreciate your work, but the magic of that is taken away when you don't know who appreciates it. I think if that cannot be implemented, maybe a like button, such as one that is available on scrolls, blogs, and articles?
