I'll never forget when I read the question, "Who is the mayor of San Jose?" on Quora, and the answer was "Joe Bloe is the mayor of San Jose. Source: I'm Joe Bloe, mayor of San Jose."
Reading that defined Quora in my mind for the next few years.
It was a made-up name for the example, since a. I don't remember the exact year; and b. I'm not sure it was San Jose -- it was some city in the bay area, but maybe not San Jose. Chuck Reed was mayor from 2007 to 2015, and I don't see him on Quora, so probably it was some other city.
Who knows? I harbored a 10% skepticism that Quora astroturfed the question. That was just the first example like that I found, in the early days questions like that were common. That should have either removed my skepticism or driven it to 100% :-)
In the very early years of Quora, quite a lot of answers there were written by experts in their area.
