Google Knol
There’s a new boy in town - Google Knol. The knol (as in knowledge) is a wikipedia of experts. Anyone can write a knol on subjects that he knows about (for experts…). I gave it a try, and written a knol about OLED, and about AdSense. Check it out, it’s rather cool (and while you’re at it, give me a vote!).
Basically several people may write the same Knol (collaborative). The experts can also enjoy the AdSense revenue on the site. There might be several knols for a certain subject (unlike Wikipedia).
