I never heard the term redditing

Haven’t used it much but something that I don’t really like correct me if I’m wrong, but basically the site has multiple servers, and each server can have multiple subreddits right? What I don’t like is that there isn’t really a r/all combining all subreddits within all servers, it’s just r/all within the server which I feel spreads the content too thin. Correct me if I’m wrong
