This would need enormous amount of human time for moderation, user support and general community management. I wonder how it went on these fronts for Google+. I don't use it actively, and from my own echo chamber not many people seem to be using it, so not a good data point. For now, the only effort in this kind of product that work well seems to be Yahoo answers. It would be interesting to see the details of what Google is up to.
