Google Knol, A Cleaner Wikipedia?

Encouraging people to contribute knowledge and to Google's own version of Wikipedia, Knol seem to be very appealing. The project Knol is by invitation only at the moment but from what I have seen sports a clean wordpress like interface.
It is almost like a group blog, wikipedia but giving prominance to people who create articles or books, not the article it self. So Geemodo will thrive to make a gee more and will have prominent place in the knol for Grid, VoIP, Medical, and social information. Perhaps I will make a knol feed at Feedotopia. Here is an excerpt from Official Google Blog post;
"The key idea behind the knol project is to highlight authors. Books have authors' names right on the cover, news articles have bylines, scientific articles always have authors -- but somehow the web evolved without a strong standard to keep authors names highlighted. We believe that knowing who wrote what will significantly help users make better use of web content. At the heart, a knol is just a web page; we use the word "knol" as the name of the project and as an instance of an article interchangeably. It is well-organized, nicely presented, and has a distinct look and feel, but it is still just a web page. Google will provide easy-to-use tools for writing, editing, and so on, and it will provide free hosting of the content. Writers only need to write; we'll do the rest."
That explains a lot. My question is why not Gnol?
