I am writing an article about the "art" of business writing, where I use this analysis to refute the usual consulting wisdom of making everything simple to grasp, even if that means taking things out of context. My argument is that sophisticated meaningful writing on difficult concepts acts as filter to identify the readers (and potential business relationships) that will be more willing to pursue visionary projects and supportive of different approaches. In this domain, you do not need or want to address the whole market, just the businesses that want to lead. Individuals who take the time to read and understand or comment, emit signals of active and insightful engagement.
Interestingly, I've seen the same argument applied as a refutation to the traditional argument that dating site profiles should be kept short and simple. Perhaps it's applicable to writing in general.
Definitely it applies to all kinds of writing, where a feedback loop is desirable, in order to establish a communication channel. In this class, the only thing specific to business writing, is that you try to establish a communication channel with a view to building a business relationship. Nevertheless, I believe there are types of writing where feedback is not desirable. When I write poetry for example, I would rather not hear from anyone who has read something I wrote.
