I think it's really not about someone taking action after they see something, the whole point behind putting something online is so that people can be made aware that it exists. The Internet is so vast that anyone really putting something on there is a shout into a void and a hope that someone can hear it, and while it may not trigger the complete end product, it will still make people notice that it's there since is so accessable. It may not be a great leap forward, however, it's still a step. That's why productions, indie bands, artists, and now politicians still make websites and MySpace because that's really the point.
