It might be helpful to add some more information to the tiles in the topics display. At a minimum, I'd like to see the number of conversations. Other possible elements are the number of posts and date of most recent new thread/post, though one doesn't want it to become too cluttered. Perhaps the dates could be tool-tips on hover, dunno. As Cake scales up, I think I may start using the topics more often for navigation, but for me the number of followers is useful only as a proxy for actual activity.
