I posted earlier about new beta software that enables one to gauge the reliability of Wikipedia posts through color-coding. New software by Virgil Griffith called wikiscanner, enables one to unmask anonymous editings to wikipedia entries made by governmental, private companies, political organizations, etc. [Thanks to Digg for the heads-up on this; article featured on this in Wired magazine.]
Community-created encyclopedias are nice, but it’s also nice to know who the “community” is that is creating/modifying these entries. It helps to restore trust around these wikipedia entries if you know that the community that is editing these entries are hired guns and can discount certain edits.
