I see Hubski as rather analogous to long-form journalism (something which obviously is pretty popular here). It's not often covered by major media outlets (at least, not the types most people tend to read, I think) and it's rarely spread in social media - the way the Reddit community tends to work, as I think we've all seen, is that people will often upvote a submitted title and not read an article, especially if it's particularly long. But, like Hubski, there are still places that longform journalism is really popular, and, interestingly, newer platforms are opening up - in New Zealand, we have the Pantograph Punch, a place for longer articles written by freelancers for the most part, and the writing quality is really good. Medium is getting more and more popular, and while it's not really longform journalism, it's in a similar vein, I think - not quite a blog post, but a similar sort of thing (mostly nonfiction work with personal anecdotes/experiences).
