Knol.Google.com - Google's Answer To Wikipedia

Imagine Wikipedia. Now imagine making money with it.

That is basically what Knol is like. Google’s version of a free encyclopaedia is currently making a big buzz throughout the internet. People who have Google accounts can add articles about what they know best, in order to inform others. The key feature is that you can place AdSense ads within your articles. For instance, say you are very knowledgeable on the subject of Hot Dogs. Write the article, place the ads, and every time someone searches for Hot Dogs through Knol, you will receive part of the profits the ads generated. The main difference with Wikipedia is the fact that people can’t collaborate on entries. If you find something wrong with someone’s article, you can’t just go in and change it. You must suggest the changes to the author, for him or her to approve them. Writing a Knol is simple, since there is no rich text formatting like in its older cousin Wikipedia.
