A big part to flag normalization would be to make the flagging option more visible.
I agree on the topic of the block chain not caring about the reasons as for one wants to up or downvote. While I also agree on the notion of people needing to grow up regarding this, I still think that some changes to flagging should occur in some way or form.
Making the flagging button more visible for example.
I think it should just be a downvote symbol when it comes to the user interface.
And I would agree with you. On the other hand, I do like the idea of positivity being more prelevant than netagivity around here. When I started around here, I didn't even know that you could flag and did not really question it.
