Google's Knol, Expert Wiki, Goes Live
Brian Jordan and other readers sent in word that Google has taken the wraps off Knol, its expert-written challenger to Wikipedia. (We discussed Knol when it was announced last year.) Wired has an in-depth look. Knol's distinctions from Wikipedia are that authors are identified by their real names (and verified), and that they can share in ad revenue if they choose to. The service initially features a lot of medical articles, which is interesting considering that Medipedia also launched today. This medical wiki is backed by Harvard's and Stanford's medical schools.
On the topic of Wikipedia-like sites, I recently found Scholarpedia, which I imagine a lot of slashdotters might like. They don't have that much content yet, and they are currently focusing on a few fields (science- and tech-related), but I have found some really high-quality articles by experts in the field, like:
Neural Correlates of Consciousness, by Christof Koch.
Algorithmic Information Theory, my Marcus Hutter.
