Via the Projects section on Metafilter comes one of the greatest website ideas in years: Fictopedia!
From the FAQ:
"One of the guiding principles of the Fictopedia experiment is to see if people can learn to live with a little inconsistency. We're so used to treating our legends and fictions as if they were academically researched, factual histories, that we forget that stories don't have to add up, as long as they are GOOD. Thus, if someone writes an article about a character and then 3 people incorporate that character in other articles in ways that are totally inconsistent (in one article he's a knight in a fantasy world, in one he's space captain, in a third, he's a private in WWII), its nothing to worry about. Its just 3 creative reinterpretations of the same character"
The possibilities are endless. For example, although this is creative fiction, the article creators don't retain any copyright control over it, so what's to stop someone from reading an article on Norwegian slam poet Arnis Radis and deciding to 'become' that person, perhaps making a few viral videos and pushing them out onto the 'Net.
For a glimpse into how the project was conceived and fleshed out, here is the original Projects thread. Watch for my article on the Bantalorean Vocal Encoder to appear soon, as I've slowly been developing it throughout my recent treeplanting days.
