OK so I have seen that people try to get their post count up to be trusted more and had suggested to remove the post count but was better idea to keep post count
Ok here it is a REPUTATION count :
When you post something good people give you some good reputation points which are green and show that you are trustworthy.
If you post something bad or useless people bad rep point you which are red and not so good.
So it would show quality and not quantity
