Wolfram Apha Is Cool
I just used it for the first time myself right now, although I have been following it in the news for a while now. I am impressed. I am going to crown it niche king. Wolfram Apha does something that Google does not, just like Twitter does something that Google does not.
It is fun. It feels like you can play with it like it were a cool toy. It takes you straight to the answer. It does not give you links to sites you might want to explore to get to your answer. It is not preparing to preparing to prepare to give you the answer.
My first search term? New York. I love New York.
