You’re going to have to explain more of the argument, because I don’t follow.
It sounds like you are arguing that writers should spend more time spelling things out for readers which aren’t very good at reading comprehension. That doesn’t seem very efficient—it wastes most people’s time, since the writer is spending more time spelling things out explicitly and avoiding ambiguity, all of the readers with decent reading comprehension skills have to spend more time sifting through crap that doesn’t add value to the text (for them), and only the people with lower reading comprehension skills get any benefit. People with lower reading comprehension skills are less likely to be reading text-heavy blogs in the first place!
The following claim may be controversial—generally, there is a tradeoff between clarity and precision, and the right tradeoff depends on the context and what your goals are. The internet, and forums like HN, distort our perception of where the correct tradeoff is, because the people complaining about lack of precision are the loudest. You should be aware of who your audience really is… is it people capable of interpreting claims in persuasive documents? Or is it people who decide to complain on HN?
