The latest view is expressed by Peter Mersch, in a discussion on Knol Discussion Board (http://knol.google.com/k/knol-help/knol-discussion-page/si57lahl1w25/204# ) under the topic Yahoo's acquisition of an article platform - Implications for Knol started by Narayana Rao K.V.S.S. in May 2010.
"I found some very interesting people here. I hope that I can stay in contact with them.
