Google will soon be releasing their own take on a Wikipedia-style of information resource – Google Knols (screenshot).
Some of the significant differences
will be: named authors (who can choose to receive a portion of ad
revenue for the “knol” pages they write) instead of Wikipedia’s
anonymous author model. The site will allow multiple “knols” on a
single topic (each will be written by a single author) with the
community voting for the best one and suggesting changes in a separate
area instead of the collaborative style of composing articles used on
Wikipedia.
