Get Some Karma #edtech

I'm intrigued by SiteKarma which is designed to give information about any web site and get a rating on the reliability of a website.  The SiteKarma score appears to be based on a number of  factors including browsing stats and whois information as well as site ratings by visitors. While there is a disclaimer that explains that SiteKarma takes no responsibility for the validity of information on any website.  It may be another good Web 2.0 application to add to your research tools.
