The PPX odds that Google Knol will become more popular then Wikipedia by 2010 have halved. Knol has been set up by Google to provide information on diverse subjects in a similar way to Wikipedia. Knol differs from Wikipedia in that each article will have a primary author.
A certain percentage of the Google share price is based on the belief that Google will develop new services that will dominate that area. In this case the market is showing that this belief is no longer fully held in this market. This suggests that if Google shares do have an “invincibility” cost built into them they could lose this.
Another result of this belief is that continued strong use of Wikipedia is likely. As such continuing to update information on the site is warranted.
