What is Wikipedia?
Wikipedia.com is a unique kind of online encyclopedia. It is collaboratively developed by volunteer users and editors around the world. In fact, YOU can edit an article if you wish. It is the most popular general reference work on the Internet and one of the largest and most-visited websites in the world.
The downside is that since “anyone” can edit the articles, and since the pages can be edited “anonymously,” the entries can be (and have been) vandalized. However, bad entries do get corrected and usually pretty quickly.
If you need some rapid info, it’s a great place to start and most of the information is very current. In fact, its very name comes from the Hawaiian word wiki, meaning “quick”)
