I understand the frustration of not getting feedback, especially when a lot of people view, but I don’t think having reputation points or those incentives will help. People who look at it and don’t reply are the type of individuals who don’t really have a desire to help others. If we added a point system, I don’t think these people would be trying anymore to give honest help, but just pad their own “helper” stats.
We have some users here who have created some popular cohorts, many of us have been in one at one time or another. You can probably see if you can get in one by messaging the creator here.
I would agree that you often get more benefit in learning things, but you can’t completely judge the community just by lack of feedback you receive.
Why is that? First you say that people aren’t replying, and then you criticize regulars for consistently replying?
