Building a combined leaderboard that pulls from two separate platforms is custom development work, and it takes real time to do it right.  We made the call to launch the new landing page without it because the existing leaderboards on DonorDrive and Tiltify are still fully active for current participants on each platform.  Also, this landing page was built for new potential Extra Lifers, not for people already deep in the leaderboard experience.  A unified leaderboard is a priority on our roadmap.  It was just not the right reason to delay a page that is already doing important work.
