Virtual worlds also provide an arena to observe social science as it pertains to the collaborative efforts of a community. Wikis Wikis are a form of virtual collaboration because they enable people to contribute to an online document that can be seen and edited by other users via the internet. Wikis are considered a Web 2.0 technology, and fall into virtual collaboration due to the collaborative process that documents go through when put into a wiki. Wikis may be described as "open virtual collaboration", which is based on the theories of living systems and includes concepts such as self-organization, chaos theory and emergence. Open virtual collaboration allows persons with a connection to the internet to seek out participation from others in the design and development of new ideas, processes, products, and services for personal and commercial purposes. Information technologies such as tagging and filtering ease the process of finding collaborators online. International Business Machines (IBM) and Procter & Gamble were early commercial beneficiaries of the practice of open virtual collaboration. By accessing the collective intelligence and wisdom of non-affiliated humans connected via the internet companies are able to access knowledge and expertise that might otherwise require significant cost and effort.
