Quora / Waste of time
Don't waste your time on this website. I was researching middle eastern politics for an assignment, so I decided to join Quora. First, Quora forces to register your email address and verify it before you can view anything. Well, that actually takes time, but many websites ask the same thing. After I was completed the registration, I checked the 'Middle East' and 'Israel' sections in which I was interested. But I realized how small is Quora's user base. And it was quite strange, but all the users shared the same thoughts about Israeli. For that reason, being so one-sided, it was useless for any researches.
