Rewards and value are different approaches and each will have a section of users persuing each. However, I believe rewards is a short term view while value a much longer one but one can’t be without the other. If we focus on creating value by engaging and supporting the community, rewards will surely come by way of the many interactions we have here to enjoy. While we do that, it we enjoy the ride it will make worth thr while.
This is generally the way it works. What many miss though si that they aim for large user follows and support more than they look to support each other. Those who grow together well... grow together :)
A balanced approach to it is always good.
