noun: 1: a small rounded hill or mound

Google Knol has taken off like a dog in a catapult, and is my favourite out of the learning websites on the web. From Wikipedia to the BBC News pages, these give a view of things "in general", Google Knol goes a step further by being essentially, an online repository for accurate information.
You name it, it's on there. If it's not, why not write about it? It doesn't have to be on anything in particular, but it's a brilliant resource to look for articles which interest you. Sure, you won't be able to find many articles which contribute to your final coursework mark, and there are no verification methods as such to show how accurate an article is. But think of Knol as a single unit of knowledge, spread over an entire website, offering students and non-students alike, a view into a different world's perspective.
