I came to know about this website few days ago by one of my friends. so far I have only been reading answers given on others questions and didn’t post any question myself. it is good place to learn new things. like now instead of browsing Facebook page I prefer browsing quora. but if you have some serious questions.
You cant trust on answers given on quora. as any registered user can answer there I found some answers very stupid and useless. people mostly give there personal opinion on the matter instead of writing what they are actually supposed to. I have used yahoo answer also and I found that one better comparatively.
