When I was still in college, I remember pulling up Wikipedia to do hasty research about a topic before trekking to the library to do some real work. However, I would sometimes discover that the information gleaned from Wikipedia was not accurate and therefore, my light research was completely invalid. Thanks to WikiTrust, you can discover what is credible and probably fake with color-coded information. The basic idea is that the longer information remains on the page without edits, the more credible it becomes. Wouldn't this have been nice a few years ago? To learn a bit more about the new WikiTrust, check out this Wired article.
