> 90% of “citizen journalism” is (trash)
You're right. But compared to what?
I guess 99% of mainstream "journalism" is irrelevant and/or inaccurate, hence citizen journalism is a 10x improvement in accuracy and relevancy! Not 10% better, 900% better! This makes a huge difference to our society as a whole and in our daily lives!
But this misses the most important point which is that the user should have the right to choose for themselves what they say and read. Making citizen journalism unduly burdensome deprives everyone of that choice.
