The leaderboard, for example this (https://secure.phabricator.com/token/leaders/) shows open and closed tasks. This is a problem, if you want to use this leaderboard to find out, which request is mostly liked, (and is open, so you can spend time). I think it would be better, if we have advanced querys for this board too, so that people can search for example: "Task with the most likes/loves in <project>". This makes it easier to find the tasks, where you want to spend your time for, so if a lot of people likes a task for example, you can raise priority etc.
