As a counterpoint; I really like threaded posts like these. Each post in the thread becomes a kind of sub-heading or meta-paragraph which allows the user to disengage at well defined stops.
At the same time, it’s understandable that people don’t like it. The format has its problems, but I find I will read less of a blog post than a thread all else being equal.
But it does not allow the reader to quickly skim the article. It requires the user to interact with each paragraph in order to enable the user to skim it for interesting words.
Old fashioned non-interactive subheadings would allow the user to "disengage at well defined steps" and also to quickly scan ahead.
