Reddit no longer has default subreddits. New accounts show /r/popular and have no subscriptions.

/r/popular is /r/all but with some more controversial/niche subreddits filtered out.

I'm talking about whatever shows up when I go to reddit.com without an account (which is all of the time)

I think you also get /r/popular. They essentially switched from a whitelist model to a blacklist model.
