I think you're underestimating a number of things that are not visible on github yet can definitely have a positive effect on the community:

1) evangelizing a technology you believe in (something I've been known to do, on here and elsewhere)

2) organizers of meetings, confs and get-togethers

3) guys who help all the time on IRC and Slack in the relevant channels (something I've also been known to do, because I enjoy mentoring yet sort of abhor the spotlight)

4) book authors... has Dave Thomas been a big committer of elixir code? I don't think so, and yet his Programming Elixir book is considered one of the best

5) a lot of other stuff that is simply not very visible, such as Jose trying to make the community more inclusive
