Google’s about to launch yet another clever idea. Called knol, it will feature authoritative articles about any topic which will use community rating and input.
It will be interesting to see how this project compares to the excellent community produced content at Wikipedia, and also how Google handles the legitimate as well as scammy SEO tactics that always follow good content. Disallowing links to commercial sites would seem to inhibit an author’s ability to feature things, but allowing them opens up the chance of abuses of the type that made Wikipedia choose to use NOFOLLOW tag on all external Wikipedia links.
The good news – more quality information online – yippee!
