For all your wordly needs you need look no further than wikipedia -the free online encyclopedia. It covers every topic under, around and about the sun and just about everything else in the galaxy. A search for something as random as a widget will bring up 384 different descriptions and wikipedia is one of the few places you can search for the meaning of life and find at least 5 different relevant answers.

Anyone can be an editor by volunteering articles, thoughts or comments becoming an honorary wikipedian in the process. So, wikipedia is good for the brain and the ego whereas encyclopedia brittanica is just good for the bonfire.
