Tools For Thought - Intelegia

For those who are frequent visitors to Wikipedia, you should be aware that there will be a slight addition to the web 2.0 based encyclopedia.

To deal with the credibility issue of submissions, a colour coding scheme will be introduced to “estimate the trustworthiness of each page” on Wikipedia. For more information on how the scheme will work, please here.

I wonder why it took so long for someone to create a system that will help users to identify sound and reliable information versus entries that may appear questionable.
