Value of aboutus.org Listings

As I was looking around at domains that have authority according to SeoMoz, one I ran across was aboutus.org. It is similar to wikipedia, but it is more about domains or websites, and there whois info and other facts. I went ahead and created a phpLD About Us page, or I should say edited the existing page. I don't know how valuable it is since this is a site virtually anyone can edit, but hopefully they have a decent editorial policy, because I know google tends to give more value to sites that are well edited, wikipedia being rated 100 by SeoMoz, and this being a similar wiki type site.
