答案 2：
Formsping 和 Qura是完全两种产品形态，而且专注的点也不一样，不存在竞争关系。fs其实是通过问答然后了解和结识新朋友。Quora更注重于内容质量的专业性，quora未来五年的计划是涵盖各个领域，军事，政治等等，当然也加入了social的元素。
本地化也是很有意思的事情，一种模式就应该由一群了解这个市场的人来做，我相信米饭和知互，及新知能做好中国市场，找到更核心的需求然后突破与创新。
建议大家可以关注一下国内的另一个形态的问答网站：segmentfault.com 【专注与程序员的问答网站】他们的产品很赞。我想很快这个产品也会和大众见面！

On Formspring, people get to know each other better by sharing interesting and playful responses that reveal their unique stories, experiences and personality.
Formspring了解不多，不便评价。
米饭是Formspring的Copycats(中性).
以下是Formspring 首席设计师Cap Watkins对Quora与Formspring的比较：
On Formspring we don"t particularly care about the correct answer to a question. We love that services like Quora do care about the correct (or maybe "best," is a better term) answer to a question. Harnessing and cataloging the world"s knowledge in a meaningful, useful way is a very complex problem and the solution on Quora is a very elegant one.That said, on Formspring we only care aboutone response: yours. There is no correct or best response to a question on Formspring. To be completely honest, we don"t see Quora as a direct competitor, especially considering our two very different focuses. It"s like comparing Foursquare and Instagram. Yes, both are social services, but each are attacking completely different problems.

虽同为社交化服务，但解决完全不同的问题。
Hope this helps！
