They can overlap with other interests and hobbies. I don’t browse UN reports directly, but I used to have access to a research service for work that would save and categorize relevant ones. Which actually makes me wonder if they are undercounting reads from other parties sharing the reports.

Who indeed matters; I’m sure for many of the reports, only several people in the world actually need to read them. I used to occasionally do research for one person to read and it was a good use of my time/salary. If it’d shared it somewhere and no one downloaded it, it would still have been worth writing for that person. However, it would’ve looked pathetic sitting out there with no downloads, compared to being printed and walked over. :)
