I was reading multiple features of bitcoin talk. Like if you get merits you can appricate others answers and also upgrade your account, add signature etc., But, when I read about trust I did not get its use. Also, in few accounts trust is only visible at the profile page which means it is hidden in the post.
Can someone please explain the uses of trust. I have read it who to get and other stuff. I am interested in its use.
Trust = feedback.
It has the same use as we do in ebay. Positive, Neutral and Negative. If you trade with anyone then depending on the experience you can leave any of the feedback.
Now here with this same Positive, Neutral and Negative you can do a bit more too.
If you see anyone is doing great job and if you trust their action then you are free to leave a positive feedback for the user.
If you find someone has bad intention or trying to cheat, harm the community then you can leave a Negative.
Use the Neutral when you do not have any side to pick for user.
These does not mean that you will need to do something (leave a feedback) for every action every user do. Most people do not care about it at all.
Now here is a trust flag which is new addition to the feedback system. More here:
