Check it: aboutus.org is a new wiki site that uses the WhoIs database to index websites then allow users to modify the listings. I came across it when I saw a link in my referer.org list down there on the left.
I think it’s cool! As a wiki, anyone can modify the contents of the listing, which makes it dynamic.
I updated all my sites’ info and created a user account. It must be really new since I’m user 8144!
Anyway, it’s interesting and if you have a site, I recommend going over there and getting indexed/updated.
