FROM THE INTERVIEW SITE...
Think about that for a minute. It computes the answers. Wolfram Alpha doesn’t simply contain huge amounts of manually entered pairs of questions and answers, nor does it search for answers in a database of facts. Instead, it understands and then computes answers to certain kinds of questions.
This is pure PR, just from the phrasing. Maybe a miracle will happen and this will actually matter to someone, i just can't see that as very likely. "Computing answers to factual questions" sounds like complete nonsense to me. You don't "compute" that the capitol of France is Paris; you look it up. It says it's not a natural language parsing engine, so i don't know what kind of syntax it'll expect.
Maybe i'm missing something major, but this sounds like buzz for it's own sake.
