Yes. I really like it and feel like it really stimulates activity. The members love seeing their avatar on the leaderboard. It gives them more exposure to the content on their profiles. A click or tap on their avatar directs members to their profile.
With the latest update the leaderboard looks really bad on iPhone, so I have removed it from the home page for now. I have been told by AQB Soft that they are working on an update. Patiently waiting.
