Well, we can now let the cat out of the bag. Google released Knol yesterday. Knol is guaranteed to generate lots of discussion in the blogosphere and press, especially among fans and detractors of Wikipedia. It is not really the same kind of animal as Wikipedia however, and we’ll talk more about this in another post, but it is something you will want to check out.

Udi Manber, was planning to announce Knol’s release in his keynote at Gilbane San Francisco last month, but unfortunately, it wasn’t quite ready. Fortunately, we had a back-up plan and Udi instead gave an excellent and audience-pleasing presentation on search quality.
