Why does no one realize there's a difference between their personalized Reddit frontpage and r/all?

Every time I see a post such as 'I've unsubscribed from this subreddit and I don't see it on my front page anymore at all!' there's a huge shitfest about people freaking out about this.

Your personalized front page has all the subreddits you're subscribed to, and shows the top posts in them.

/r/all shows the top posts across the site. If you've unsubscribed from one of the subreddits with a popular post, it'll show up regardless (unless you've filtered it with RES!).

It's not that difficult to understand, but people sure do get angry about it!

Just thought I'd point out the difference.

Hope everyone's having a nice night.

TL;DR there's a difference between www.reddit.com and www.reddit.com/r/all when you're logged in.
