What impact do you think you can have on the world?

Why I care? I don't know, I really couldn't put it in so many words :). What brought me? "Curiosity". What keeps me here? The conviction that we can change certain rules, that knowledge can be free for all. What impact? A tremendous responsibility about the way knowledge, education of another kind are brought to people. What impact I would like Wikimedia to have? I hope that Wikimedia manages to change the rules about "freedom" and "dsitribution of knowledge" while respecting differences and cultures (may they be national corporate, social, personal...).
