I really don't know how to explain it... the site says:

Making the world's knowledge computable

Today's Wolfram|Alpha is the first step in an ambitious, long-term project to make all systematic knowledge immediately computable by anyone.  You enter your question or calculation, and Wolfram|Alpha uses its built-in algorithms and growing collection of data to compute the answer.

Big deal, I'm approximately 741,100,000 seconds old - beat that!

[Byron]

I can't, you're 95,900,000 seconds older than me.

At least it knows this:

It's nice, but it doesn't have many answers to my special questions.
