I have just been doing a little bit of research about Knoll. It’s a new Wikipedia like site put out by Google. Instead of articles that are editable by everyone, the articles on Knoll are from experts, or at least people who purport to have expert credentials. The idea behind this is that the information should be more reliable if people are willing to attach their names and credentials to the articles.
Speaking of articles, there are a lot interesting articles already on Knoll. I am surprised at how quickly the breadth of Knoll’s offerings is growing. I assume that very quickly it will be a serious contender with Wikipedia. For example, there is already a Grand Theft Auto 4 walkthrough on Knoll.
