CloseReview for Wikipedia by Shaun Anthony
Rated 5 out of 5 stars
Wikipedia is a great resource for quick, accurate information. You won't be able to use it as a proper source for academic research, but it satisfies most of your curiosities. I don't understand why it's not a default search engine already.
