Wolfram|Alpha’s unique selling point revolves around its rather impressive ability to understand natural language queries, and then fire back fairly well composed results in an easy to understand format. Think of it as the text version of the Enterprise’s computer on Star Trek. I just spent a bit of time playing around with it this morning, and I have to say that while it’s clearly still early days for the engine, it’s already worth sharing the stage with the Googles and Wikipedia’s of the world.
Of course, I suppose it’s only a matter of time before Google acquires them? 😉
