Google Answers Retrospective
It’s always fun to look back, and there are some truly amazing questions and answers at the now-closed Google Answers service (like How many Giraffes live in Canada).
Andy Czernek, who was omnivorous-ga at GA, has put together 365 Days of Google Answers, a daily calendar where he draws attention to an interesting question for every day of the year.
You can read the whole year at once, or savour a question every day. There are also some search tips and other useful snippets.
