Well, maybe 200 or 50 or even 10 years ago it was a lot harder for one person to make a difference (unless that one person is warren buffet or something) but today with the ability we have to communicate and collaborate... I mean, look what happened to Dan Rather in the 2004 election cycle. He puts forward some 'documents' disparaging Bush, and a handful of people realized that something was amiss, and it wound up being a huge scandal for Rather. I think that was the point when people sat up and realized the internet could be good for something not related to porn ;)
