The Story of the PING Program In many ways, this is open source before open source, in that it's one guy with an idea who sits down one evening and changes the world in a small but significant way. That, to me, is the real revolution of the internet. Sure, you can buy stuff online, you can download stuff (pirated or otherwise), you can even make cheap calls, but the crux of the medium is the sharing of ideas. It is an incredible, unfathomable medium for ideas, be they bits of code, songs, films, discussions, or documents of trade, business or research.
Another fine example of this is Bram Cohen's BitTorrent, which is nicely covered in an article here.
