[detrites]

Counting subreddits is meaningless as a stock percentage. For example, there are millions of subreddits, but only 150k or so even have any activity at all. A small percentage of those are responsible for most activity.

The number of users impacted by the (very popular) subs that have gone dark looks in the region of almost... everyone.

What will reddit look like without r/pics? Without r/funny? Without r/Music, t/aww, r/todayilearned, r/explainlikeimfive, r/DIY? Etc.

Less than 1% of all subs are going down, but it's substantially comprised of subs that matter the most, appeal to the largest number of users and literally have characterised the site as a whole for over a decade.
