I think it’s worth revisiting this post by Laurie on a regular basis for a shot of perspective and inspiration.
The web saved my life and then built me a new one. A single living entity, it touches everything in the world and is always getting better — and I can help. I owe it so much; if I can help it out, make it better in any small way, how can I possibly refuse? And if I can make it easier for other people to help make it better, then my efforts are multiplied.
