Quora is a well built platform on which one can get knowledge about anything he wants to learn such as languages, places, science, commerce etc. It helps me a lot with my studies and I can browse throught it for answe o any question I want or ask question to those who are knowledgeable in the field
Next point is the quora is a platform on which main everyone is educated or literate so the answer you receive for any question is always through the point and generally accurate supported by facts and figures. Which is nice way of learning something.
But with education also come ego. On this platform you will find many people boasting about their knowledge and showing there richness and much more so every coin has two sides it is true for quora also.
