Collective intelligence has risen with the internet as loosely organized crowds have solved problems through websites like Google, Wikipedia, and Threadless. While groups are generally better than individuals at solving problems, critics argue that collective intelligence is bad for creativity and unconventional ideas. The key aspects of collective intelligence are who participates (hierarchies vs. crowds), why they participate (money, love, glory), what the group does (create or decide), and how the group makes decisions or works (voting, averaging, markets, consensus, collaboration, or independent work). An example is the collective intelligence used to develop Linux.
