Wikipedia is the best resource for finding any kind of information but then again all you is one page with links. If you dont know how to search wikipedia it can be a big mess. This problem is smartly answered by Powerset. This application searches wikipedia but what makes it rock is the search result

The search result is divided into 3 major sections, First are the straight facts or the firect summary of information. Like when I searched for Elizabeth 2. I got a small summary and her basic information like date of birth. This can satisfy most of the people.

The second section contains set of factz on that term collected all over from Wikipedia. Factz are information compiled from pages across Wikipedia. They are expressed in 3 parts, two “things” connected by a “relationship” .

Last section conatins links to the topic you searched for. This is like google search result but the difference is , there is a miniviewer for each fact which again has 2 sections article and images i.e. Its like brining the normal search and image search together.
