According to Wikipedia, “wiki”, a word that in Hawaiian means “fast”, is computer software that allows users to create and edit web pages collaboratively.  Wikis are being used increasingly by businesses to provide information Intranets.  It is surmised that there are many more wikis behind firewalls than on the public web.  However, wikis have a use as a Web 2.0 tool.   Individuals may design their own wikis using “wiki farms.” Wiki farms are wiki hosting services.

Two very popular wiki farms are PBWiki and WetpaintWiki.   Both wiki services stress ease of use.  PBWiki’s (or PeanutButterWiki’s)  slogan is “Make a free wiki as easily as a peanut butter sandwich!”  WetpaintWiki also bills itself as user-friendly, a site where one can make a wiki in three easy steps. Both offer ad-supported free wikis, although PBWiki also offers a paid ad-free account option. 

The PBWiki home page is geared to providing information about how to set up a wiki and includes a link to a wiki demo.  Tabs allow users to see examples of wikis and wiki features.  Specific tabs are provided for businesses and educators.  PBWiki appears to more geared to this market.  This site stresses the services such as enterprise-grade encryption and automatic backup, as well as the more advanced security options such as hide-able and lockable pages, offered in its paid premium account. 

WetpaintWiki appears to be geared to more non-technical users wanting to collaborate online on interests such as art, music, and hobbies.  The main page offers many themed wikis that can be easily accessed by users.  Seasonal wikis (currently Halloween) are highlighted. In keeping with the emphasis on collaboration, WetpaintWiki has started a Facebook application entitled “Whiteboard” which allows Facebook users to “collaborate wiki-style” within Facebook.  There are business and education wikis available on WetpaintWiki but information on site security is not easily found.  

A more technical review of these two sites as well as a complete comparative listing of all wiki farms can be found at Wikipedia’s “Comparison of wiki farms.”  Both sites offer opportunities for libraries.  Libraries can create their own wikis on a topic of interest to their patrons, link to other wikis of interest, and teach patrons about wikis.
