Born in 84. I have been a user of all the above. The reason I mentioned GitHub to this level is truly in 2009 onwards it unlocked sharing of code at a level I had not seen before. It really did eclipse the reuse of software to what came prior and a lot of that has to do with the associated social network and network affects. They in a way game-ified software for a new generation. And it's not that we didn't share software before, just not to this degree and that's because every decade we rebuild the same ideas for a new generation that then 10-100x what came before. So something will come after GitHub as well. But today that's what we have and that really changed software for a generation.
