I don't know if anybody visits the site tvtropes.org, but there is a surprisingly large amount of information under Jin Yong. I haven't checked out the Gu Long part yet, but it really makes me wonder who they have working on that site to get such a huge amount of information on so many topics.
It's a fun read, even though the topics are more mundane than the ones we usually discuss here.

Edit: Beware, if you've never been to the site before, it sucks up more of your time than Wikipedia and Facebook combined !
