nam37 wrote in about a Macworld article which reads: "Google
Inc. on Thursday began delivering factual answers
for some queries at the
top of its results page, to save users from having to navigate over to other
sites and look for the information. For example, if a user enters the query
'Portugal population,' Google returns the answer -- 10.5 million -- along with a
link to the Web page where the information came from, which in this case is the
population page of the U.S. Central Intelligence Agency's Factbook. The
query 'who is Jane Fonda?' triggers the answer '... is an Academy Award winning
American actress, model, writer, producer, activist and philanthropist' and
provides the link to the Wikipedia online encyclopedia's entry for the actress.
A small percentage of queries currently trigger these factual answers, but the
service, called Google Q&A, is in its early stages, said Peter Norvig,
Google's director of search quality."
