RigVeda Wiki, more commonly known as Angelhalo Wiki, is a Korean wiki site which uses the MoniWiki engine. It is often described as "the TV Tropes of Korea" for containing various articles and references to pop culture. Unlike TV Tropes, however, this wiki describes its articles with an encyclopedic "feel" to it, although in an informal manner. It has a document count rivaling that of TV Tropes, reaching 185,621 pages as of mid-February. However, it pretty much lost its functionality after most of its users abandoned the site because of their gaining commercial revenue while using the Creative Commons non-commercial license.
And of course, it's mostly in Korean.
