This website was created by Chris Harland as he felt that the individuals at numbersAPI created something too full of nerd goodness not to be put into immediate widespread use.
After about five minutes of reading number facts and trivia I was looking up various topics on wikipedia. So what better way to get motivation to learn a quick new thing than to jump off from your twitter stats?
This site also features components from a more ambitious sentiment analysis project. I figured I would throw this up for people to use in the mean time.
