Quora has released its “Best of Quora 2010-2012″ book to the public. The 400 page PDF file features the best answers (over a hundred) in 18 categories—everything from tech to food to life advice. So, if you ever wanted to know, “what are the best stories about people randomly meeting Steve Jobs,” look no further than this free download. Back in October, the book was provided as way to express its gratitude to its top writers, but I guess Quora now wants to say thank you to everyone. [Source: Quora]
