I do not get it.
I post my articles only when I believe they are good. Hence, the positive feedback wastes my time and the readers' time. If you, as a reader, find my piece worth praising, tell others. Do not waste my time; I already know that my article is good.
I seek feedback telling me about weaknesses in my writing. Was my logic not coherent? Was I inaccurate with facts? Please let me know about any other faults.
One might call it negative feedback. For me, it is positive. I value it even when the critique is unquestionably unjust. Let other readers know my critics and their arguments.
