There may be no service on Earth full of as much spurious misinformation, confusion and doubt as Yahoo Answers. There’s a sense of 100 monkeys at 100 typewriters with the occasional answer breaking for freedom with a whisper of welcome sanity.
By contrast, I think Quora has more potential, and many agree. However, there are a good number of people out there who think it’ll never expand its appeal beyond the small group of techies who are currently singing its praises.
I think they’re missing the point and underestimating where Quora is in its lifespan.
