Knol

Also, Google launched a "Wikipedia rival" though I don't think it's really that. It's closer to wikihow at this point, and it's called Knol. It just launched, and it looks like most of the articles are health-related, but it has the one thing that Wikipedia doesn't - a rating system! Seriously, I've been waiting for Wikipedia to do something like that for a long time, and it really makes sense considering the volume of traffic...
