Wikipedia, the free encyclopedia
One of my favorite references on the web is Wikipedia, especially when I'm trying to find information on something I know nothing about. Wikis are usually collaborative compliations of information hyperlinked together, much like what the web was intended to be before the advertisers were drawn in to help pay for the bandwidth and server farms. For more information, see Wiki. If you're interested in creating a wiki for a project or group, this easy-as-a-peanut-butter-sandwich wiki could be just the ticket.
BTW, if you're one of those editors frustrated by poor punctuation and spelling, wikipedia offers some wonderful opportunities for you to make corrections instantly!
