See, I don’t think it is. While Reddit has many, many problems, most users seem to be okay with it. Heck, until about year ago, there was a subreddit called WatchRedditDie which had ample proof of Reddit’s shortcomings. However, Reddit never really died, corporate interests just took over. After this revelation, the mods of the subreddit rightfully gave up and archived the subreddit. I believe Reddit will only die when a mass exodus of users takes place, which is just not happening right now.
