Google too wanted to celebrate my birth day and hence released Google knol (a unit of knowledge). It struck me immediately as I was looking for similar tool to make my GateGenie book public. Well, GateGenie is a book for Computer Science GATE preparation. As I am growing old, I am finding it difficult to keep the book updated and hence wanted a platform where I can upload the book and then the users can comment/update which I can moderate. WIKIBOOK was one of the options but then I loose the control and no revenue once I make it public.
It is one page knowledge that one can share with others. You are the author of the page. You can invite collaborator/reviewers etc. There are three levels of licenses (open, non-commercial, copyright) and three levels of collaborations (open, restricted, closed). In the restricted mode of collaboration registered uses can suggest changes to be approved by the author which is a very useful way. You can also earn using google adsense. Adsense was one of the feature I was looking for and I got peacefully. In addition it also has Name Verification option which if done will put a seal against the knol/author. This way the reader will be sure of the identity of the author.
As its recently released, only few articles, mostly in medical science are available as beta release. But I guess with Google's aggressive way, the tool is going to rock. In all, a cool too if it satisfies your requirements. In my case, it is perfect.
