The general reference reader-edited online encyclopedia, Wikipedia, has spawned niche sites based on the same model and design. I stumbled on the domain directory wiki, AboutUs, which is self described as the “free directory about every domain in the world that anyone can edit.” This may be an advantageous supplement to your favorite domain whois.

And there’s a wiki for news junkies.WikiNews is similar to Newsvine, a participatory site that collects current news from readers and the major outlets.
