At AboutUs we are creating a vibrant place for community comprised of members sharing their knowledge.
We are a wiki, an open edit platform different from other websites in that anyone can contribute. As such, the more people that read and edit a wiki page, the better it gets - like polishing a pearl. At AboutUs we envision community to take the form of active visitors contributing and helping to build the commons in the way that suits them best. You can participate by creating a personal page to link with others who share your passion, or develop portals--deep, data-rich resources--in your field of interest or expertise.
