My writing on Knol during July 2008 to November 2011 resulted in a knol portfolio having 100,000 page views per month.
1300+ page views gives Alexa 100,000 rank
I reached up to 4300+ pages per day.
I am now moving back my articles to blogger blogs from Knol. I did number of Knol book collectons. They will go to Annotum-Wordpress blog. But individual articles will come to blogs.
My new blogs to post knols are
