I like and support this idea of rewarding comments, although this is a very complicated task due to the subjectivity involved in this process. Not always writing many characters to express an opinion or reinforce the theme of the publication previously read implies that the comment is of a certain quality. It is right to encourage participation, but it is also important to reward with greater weight those that induce the community to debate respectfully or positively complement the author's work.

The truth is that I don't know if algorithms have the capacity to detect the complexity of what a person wants to express from the depths of his brain, beyond the extension of what is written, quality should always stand out, at least that is what I think, however, perhaps the competitiveness that this mechanism you explain induces in the community can make the qualitative process of the responses increase as the quantitative is multiplied. Greetings.
