In my opinion, there are no need to pointing, thanking, medaling or reputation systems. I see a lot of useless posts which were sent to increase their post counts and when I login to forum it is taking time to read them but the conclusion of contents are nothing. Is this not a waste of time? The forum is very good as what it is currently (now) without these systems. I (or may be most of us) need good/clear posts, solved problems/requests and to improve my/our engineering.
