Knol, as the new online encyclopedia written by internet users will be called, will show a photo of the entry author, won’t allow visitors to modify entries without the original author’s knowledge, and will enable entries “written on the same subject to remain separate and compete for the attention of visitors, who will be able to give online feedback.”
If you want to get involved, go here: knol.google.com, where there are lots of articles about genital warts, constipation, cancer, nasal polyps, buttermilk pancakes, orchid basics and the like already there!
