Knol – Google’s Wiki is opened for business
The most attractive difference between Knol and Wikipedia is, you can place adsense on your pages (or as they call it, your knol). That is the most attractive which I think should get your heart racing a beat or two. So if your page gets more popular, you get financial rewards too.
Other major difference is that, nobody else can edit your page. They can suggest the edits, but only the author can approve it or reject it. Once you’ve logged is using your Google account, your name will be displayed and published. To add some authority to your pages, you can verify your real name by using a phone or credit card.
So there’s no anonymous accounts behind a knol.
Google also encourages different knols on the same subject:
The key principle behind Knol is authorship. Every knol will have an author (or group of authors) who put their name behind their content. It’s their knol, their voice, their opinion. We expect that there will be multiple knols on the same subject, and we think that is good.
Adding adsense is easy, just enter your email in the settings and your address postcode.
This is another alternative for you to share what you know and hopefully, get financial rewards along the way, albeit only through adsense, without going through the hassle of maintaining a blog.
