I do feel I am part of the first group. I started out mostly getting the help, getting the information, and consuming it to better myself in the skill that is PHP. Since quite a few years now, I've also been trying to give something back. First by helping people in the support team of an open source app, later by contributing code, having my own blog and even speaking at conferences now. But even now, I still read as much info I can find on PHP and related topics, to improve my own personal knowledge base on those topics inside my head wherever I can :)
