Hopefully this list can become a place where people can go when looking for examples (eg. if a member answers lots of lilypond questions you might check out their GitHub and see if they've got any samples), or to learn a bit more about the various people on this site, their backgrounds, etc.
Please edit the CW answer below to add yourself to the list.
