Google Encourages people to contribute knowledge through Knol
Google takes on Wikipedia with Knol - The idea is called Knols, or “units of knowledge.” “Knol”, just announced at the official Google blog, is a currently private, invitation-only knowledge sharing service.
Google’s Udi Manber says, “Our job in Search Quality will be to rank the knols appropriately when they appear in Google search results.” Knol pages will be made available for indexing by search engines, Google announced.
Will Knol be same as About.com ? Will it destroy Wikipedia !! wooooo!! . So that it can be called Googlepedia ??
Here's a screenshot of Knol from the Official Google blog :
