All my GH contributions have been to private/corporate work. sigh yet another barrier. All my contributions before that were before github existed. Since then, I don't know what to work on in public as it's not actually that obvious where to find interesting problems when web is not one's domain. But I guess that's the perils of being an older programmer.
