Quora blocked me, they claim, for not using my "real" name. Truth? I had the audacity to disagree with & then block one of their favorite members. If you're into high school antics, if you are a good sheep, Quora is for you. If you are intelligent, an independent thinker, if you like to share ideas to gain knowledge there are many forums/sites available, Inspire is one I would recommend. I have blocked Quora & yet they continue to email me. Quora was started by one of the individuals that started FB... enough said.
