The search engine on knol is not working. Authors are still able to edit their own knols and write new knols. Visitors are able to access knols through engines. But Knol is getting good publicity (amount of publicity) and bad publicity because of the outing. Why bad publicity? Because for quiet sometime people are quiet about Knol. Now they got a chance to write.
But on Knol things are improving in terms of new knols posted.
