In 1999, David Anderson launched Seti@home and with it a method of enlisting the underused cycles of PC's worldwide. While Seti still hasn't found any extra-terrestrial life, it did give birth to BOINC (Berkeley Open Infrastructure for Network Computing) which Anderson established in 2002. The Economist, December 6 edition, reports that BOINC based computing supports several hundred CPU intensive scientific investigations and has recently been augmented to use PC graphic cards and Playstations for some graphically demanding processing.

The article also identifies some social applications of BOINC of interest to museums. Galaxy Zoo has employed more than 100,000 volunteers to examine the Sloan Digital Sky Survey to classify galaxies and Stardust@home is using volunteers to spot stellar tracks. The Manchester Museum has had volunteers cataloguing 12,000 herbaria specimens from the 19th century. Africa@home from the University of Geneva is enlisting volunteers to extract cartographic data on the location of roads, villages, fields etc. from satellite images.

Projects like these have led Anderson to launch a new platform he calls BOSSA (Berkeley Open System for Skills Aggregation) which he hopes will be lower the barrier to entry for such web-based knowledge sharing and collaboration projects.
