I was originally a member of the web payments community group which existed before payments was on any standards track at W3C.
The high level of interest and activity in the community led W3C to form an interest group to explore if payments was a WG-worthy topic and I also participated in that.
When we finally chartered the WG I was approached to chair and agreed. We've re-chartered twice since and I continue to chair.
The job is made a lot easier by the fact that we have a great W3C staff contact who does all the heavy lifting.
