2009年，兩位前Facebook員工Charlie Cheever和Adam D』Angelo（時任Facebook首席技術官）以邀請制起步創辦Quora，吸引了眾多矽谷精英和名人，包括他們的前老闆Mark Zuckerberg，隨後逐步向公眾開放，因其始終高質量的問答而備受推崇。
他在長達1000多字的回覆中控訴了美國政府兩次海灣戰爭直接殺害無數無辜市民，以及美對伊拉克的制裁使得當地人民間接生活在死亡邊緣。回答中他說，90年代由於制裁導致的大蕭條，他們一家五口人每月收入只有5.5美金，而這也是普通底層政府官員的平均工資水平。
當事情出現稍微好轉的時候，2003年美國又打著「拯救伊拉克人民」的旗號卷土而來，從而使他們的生活從安全但極度平窮，變成了富足但極度危險：「People had one Saddam to be afraid of, now they have hundreds! They used to live safely by keeping their mouth shut, now they can't even if they do.」
他說現在他們一家的生活已經相對好一些了，尤其是經濟上，父母一個月有3750美金的工資。但是他的弟弟經歷過一次汽車爆炸(car bombing)而他自己經歷過四次。幸運的是，他們都還活著，而這也僅僅因為他們生活在巴比倫，一個相對安全的城市。
當然，被選為最佳的答案不一定是最正確的，甚至可能是主觀的、偏激的。如果有興趣，你可以通過每個回答最後的網址連結，找回最初的這道題，去看看更多的其他人是如何回答的，或許有助於你更全面地去了解這一個問題。
高質量的回答，即是由真正從事這些職業或親身經歷過的人給予的。那些我們想像中酷炫刺激的職業實際上卻是枯燥亟需忍耐與安靜的，患有艾斯伯格症的Alex向你講述他因缺乏社交感知力下的生活，希爾曼家族的人告訴你他富豪家族的真實生活是什麼樣的……由此，形形色色的生活、我們從來沒有機會經歷的場景可以栩栩如生地展現在我們眼前。這些回答或許個人片面，或許顛覆認知，但卻是真實而誠懇的分享。
另外還有前面提到過的「監獄生活篇」，4篇最佳答案出自4位囚犯之手，碰巧（或者並不偶然）的是4個人都是來自加州San Quentin監獄 (註：號稱世上最貴的監獄)，似乎正合了其中一個問題想要尋求的答案：「在San Quentin的囚犯是否有電腦可以上網？」
