This blog post is from 2009, I think Wolfram Alpha was pretty new back then. It would be interesting to know what he was looking for and if it still isn't there. His example of a query that doesn't work seems to return data now, when typed slightly differently: Not working link taken from blog post: http://www.wolframalpha.com/input/?i=graph+u.s.+unemployment%2C+graph+u.s.+minimum+wage http://www.wolframalpha.com/input/?i=graph+u.s.+unemployment... Working result: http://www.wolframalpha.com/input/?i=graph+u.s.+unemployment+vs+minimum+wage http://www.wolframalpha.com/input/?i=graph+u.s.+unemployment... I think it would be great to have a nice open source symbolic math package with a good UI, but for the 3 times a year that I need to know how to factor some equation like (x-1)/(sqrt(x)-1) , wolfram alpha does a pretty good job! I need to explore sage and mathics more, they both look cool
