Remember Google Knol?
Google Blogoscoped takes a look at the current state of Google Knol, Google' almost-forgotten, and allegedly more "authoritative" response to Wikipedia. Knol launched with much fanfare in 2008, although plenty of skeptics at the time felt the walled garden approach would fail.
Since the last time you've heard anything about Knol was probably in 2008, it's probably safe to say that it is now a failure. Will it recover? Google Blogoscoped says the developers seem to be "taking a long term view" of the project, and notes they are still actively improving the service. But the post estimates that Knol only has about 163,000 articles on it, many of which appear to be spam or debates about Knol itself. (Wikipedia has 3.2 million articles in English alone.)
As a result, few people seem to be thinking about or looking for Knol. Some Google Search Trends charts included at the bottom of the article dramatically illustrate this point. (The blue line is Wikipedia, the red line is Knol.)
Have you used Knol? Contributed to it? Made any money from it? --ADM
