After a lot of feedback, I've updated my landing page to clarify what Tardy does. I'm trying to keep it as clean and simple as possible.
If there's more things I need to change, don't be shy to let me know.

Okay the idea is neat, but how does it work - what happens if people are always late? they get bad points and so what?
The late person will be ranked at the bottom of the leaderboard. You think anyone will want to have future meetings with that person? They will have a bad reputation. Hopefully that will entice them to change their late habit. Still working out some details :)
