Though I think that the content of a wiki and blog would be different I imagine a blog would be more about current analysis and opinions on players and teams, while a WNFF wiki would be more about jokey player and team profiles compiled by the more humorous members of this board. Or are you suggesting a serious Wiki?
I'll admit the first things that came to mind were "in" jokes and wnff meme type things
but a serious one isn't a bad idea.
