> One of the strengths that's getting overlooked here is that crowd-sourced news seems to be more reliable than news from any one source. Everyone is biased, but if enough people are talking about something the bias tends to cancel out.

I don't think that is true at all in general. If the opinions are divided like 50/50, perhaps yes, but what if it's 75/25 or 1-versus-the-rest?

Also, most people find themselves effectively in massive echo-chambers, and the amplification factor of resonant opinions may not be very predictable.
