Sincere writers with the intent to truly inform, will write to the level of their audience. If they are missing that mark, the readers will provide feedback and the writer should adjust their writing accordingly. If this feedback is ignored and the writer continues with the same approach, it is very evident that the writer is not writing ‘to' their audience, but is writing ‘at' their audience with the simple intent to impress and not to inform; and the only thing being impressed is the writer's ego as his audience silently walks away with a sigh.
That is very true, and it goes both ways. Now, who is the audience for this discussion?
