Google Knol Invites Knowledge Contributions

Currently available by invitation only, Google's Knol tool is for experts wishing to share "units of knowledge" online. Posted on Google's Blog and first reported on SearchEngineWatch Forum and Google Blogoscoped Form, Knol invites readers to "voice your opinion, write your own knol" and includes elements like by lines, wikis, article ratings, author rankings, views, edits, peer reviews, comments, resources, book listings, references as well as an area for reader comments. Knol includes options to use licensed images from sources like Flickr and ads by Google. Google says they will not edit or bless content posted by Knols.
