Wikipedia may be adding a color-coding tool for users to mark questionable content on the site. This tool will first be tested out on various sites within the Wikia suite before being applied to Wikipedia.
The option of color-coding will be a way for Wikipedia to address the concerns regarding the reliability of entries, as they can be created and edited by anyone. With more tools for not only editing content, but marking questionable content, this will help the reputation of the site overall, as well as the reputation of the individual contributor. Those with the least amount of revisions will have a higher trust factor. This has been the major issue with Wikipedia, and bringing in more useful features for increasing the ability of the community to ensure more levels of quality control will only help Wikipedia further.
Other wiki-related developments include Search Wikia and Similpedia. See also: The Wiki Toolbox: 30+ Wiki Tools and Resources
