What is Google Q&A?

What is Google Q&A? You can now enter such questions to google and get an answer immediately, for example "when was president George Bush born?" gives you his date of birth, it's a new Question and Answering technique, that could save you a lot of time!

The tool still needs a little finetuning and not all questions are given with a short answer. But the idea has a great potential says some people, because that is what you want, you do not want to keep searching for the right answer, but just get it on your first attempt.
