I may still be alone in this, but I as I explored with WalkScore's Matt Lerner here, I believe this tool, whoever finally perfects it, has revolutionary potential. It can easily be converted into a two-digit transit score which, unlike the WalkScore Transit Score, actually describes people's ability to get places. But it's bigger potential is as an alternatives analysis tool. When you city is facing a series of possible alternative transit projects, what if every citizen could use a tool like Mapnificent to see the exactly impact of each alternative on their mobility, and that of people and destinations they care about.
A major problem in transit politics today is that negative impacts of a project are obvious but benefits are often described in terms of ridership and development outcomes -- things that don't matter to the selfish present-minded citizen. We will always have selfish present-minded citizens, and I'd rather work with them than complain about them. Until we help people see the way a proposed project will change their lives for the better, sensible transit projects will continue losing these debates.
