Your comment actually says you do agree
irrespective of the fact that they win or lose
The winning part has nothing to do with commitment! It's a fact. Engaging and participating and doing it consistently: that's commitment. While some put in more effort than others everyone has the same chance of winning. And I guess that's ok. In the end people who engage more and write quality comments and responses are rewarded more by the engagement project so there's definitely an incentive for that, besides it's much more fun and fulfilling :-)
Absolutely. The lottery is luck but the real reward is what comes with people willing to engage with you because they find your thoughts worthy.
Very true!
