The majority of answers to questions I explored on Quora are constructive, helpful, thoughtful, and possess merit. I value reading multiple answers from people around the world, and I appreciate when people provide info about their credentials. While there are a few unhelpful, self-serving or negative responses, the majority reflect positive, well-meaning people offering truly helpful responses. One thing I like about this site is the focus on constructive dialogue even on contentious issues (very little in the way of rude, offensive, or judgemental language -- people leave crude language, profanity, etc. out of their responses (or I guess they are filtered out). Collapsed answers, which are not readily promoted, generally failed to answer the question in a helpful way or to provide supportive evidence for some of their responses; they might simply express a rudely worded opinion without any support or justification -- not really helpful. Quora is not meant to be a venting medium, and I value this about it, too. It focuses on exploring answers to questions. I have found this site very helpful. My one caution is that the information is given in goodwill, as I understand, so if you are sharing unique ideas there's a possibility others may use your ideas to their own advantage (publication, etc.). I'm not sure what the copyright is on the information you provide. Otherwise, I have found this site helpful, intelligent, and full of well-meaning exchanges of info between people living in various communities around the world. I love it!
