Fulfilled commitment is a term used but never actually explained. I'd like to know what it consists of because it is a an important aspect of this launching site. It clearly differs from "Commitment" and I'd like to know why.
I think clarity will improve the user experience and will motivate people to participate and... well, commit.
There is some Q&A present but nothing confirmed and also really dated (~5 years old). The FAQ only mentions "Once you've fulfilled your commitment on a new site by asking and answering a few questions" which is rather vague.
