Abstract

The Internet is a huge form of social capital that is not reducible in its characteristics to other forms of social capital, such as ordinary networks of people who more or less know each other. It enables us to do many things with radically greater efficiency than we could without it. It can do some things better but other things much less well than traditional devices can. At both extremes, the differences are so great as to be not merely quantitative but also qualitative. The things it can do better include things that can readily be checked and verified. The things that it often cannot do include securing commitments for action. A brief history of the forms of social cooperation suggests that relationships on the Internet are typically too thin to back trust and cooperation among those who do not have fairly rich relations hips off-line.
