Hey There,
I am very much impressed by the move taken by you mentioned in the first point. Its a very genuine one to go with. Knol is getting on par with wiki these days and the type of description they give is very interactive. I remember when I was searching some article about the admission in to US Universities based up on your GRE scores. The results they gave me saved me 150$ and I was capable of deciding my university based on it and finally got an admit recently.. Or else I d have to pay 150$ to a consultancy..
P.S: I hope I am the guy you were mentioning in the second point
