Yes, for the subjects that Hacker News is concerned with, but there is a lot more out there than just what appeals to this techie crowd. As someone who has been involved in travel blogging, for example, I have witnessed long-form text becoming less and less popular, and instead images or video are taking over. Obviously it is all well and good to show people things, but there was a lot of useful detail expressed in longform text that you don’t get from the low-information-density formats popular today.
