Andy, yes, but I'm not sure this is an adequate metric. More significant is well focused developer hours, plans, customer focus, profit etc.

Is Moodle “Bigger than Martin”?
Likewise, if you’re not embedded in the Moodle community, you may not know how central Moodle creator Martin Dougiamas is to that project, or even know who he is. And yet, he is huge. I can name maybe a handful of people who are relatively widely known and respected in educational technology. I can name only a few who are admired and even beloved. I can name very few indeed who are not working for universities (although that’s changing a little, now that Jim Groom and David Wiley have both joined commercial ventures). Within the circle that knows him, Martin’s many admirers have been fiercely loyal to and protective of him, trusting him absolutely to steer Moodle the product, Moodle the community, and Moodle the brand. When you add to that the size of Moodle’s adoption footprint, one can make the case that Martin Dougiamas is one of the most consequential figures in the history of educational technology.
