The last several years have seen intense interest in developing technology that improves our connectedness (see “Tagging Is It,” p. 21). In part, that interest was spurred by the phenomenal success of open-source software, which is built by communities (see “How Linux Could Overthrow Microsoft,” p. 64). It also reflects the success of Google and eBay, which have profited by harnessing the collective behaviors of very large groups. Connecting technologies like online social networks and Web logs, or “blogs,” are familiar to many people, and wikis–group Web pages that any member may edit–soon will be (see “Larry Sanger’s Knowledge Free-for-All,” January 2005, p. 21). Technologists, then, are already attacking the problem of how to achieve a high group IQ.
