I agree that the internet has enabled a great deal of various kinds of collaboration. IMO, Wikipedia is the most complete, and generally the most useful - summing over the whole of the world population - product of this. Regarding charities: again, summing over the whole world's population, Wikipedia delivers an enormous amount of good, for a paltry budget of $16 million dollars per year. For me personally, it turns every month several hours of tedious research into exciting, enriching learning and discovery experience, often providing insights and connections which might not have happened otherwise. I imagine hundreds of millions of people around the world are in a similar situation, and the total benefit (I think... YMMV) far outweighs even such great charities as Red Cross, whose budget is about 100 times larger.
