Wikipedia may be the best known but it is not the only example of a group of people attempting to build an on-line knowledge bank of information. There are other fish in the sea.
Armeniapedia is an Armenian focused wiki. Starting in 2004 by Raffi Kojian the wiki covers history, culture, food and other topics with an Armenian or Armenian-American focus.
It invites contributions from the community. There is user generated information on this site in English and in the Armenian language however there is content from other sources that is citied and used by permission. http://www.ameniapedia.org
