When committing to a proposal, you commit to asking/answering 10 questions when the site gets into beta. I have done that on one of my commitments but it hasn't moved to my 'Fulfilled Commitments' section of my Area51 profile. How does the system determine when you have fulfilled a commitment?
According to your posting history on [philosophy.se], you've asked eight questions and answered two—which yes, should fulfill your commitment.
However, as three of those posts were just made in the last hour or so, I'd say give it some time. I suspect determining commitment completion is part of one of the jobs that runs overnight.
