How I understand it so far

It’s like someone who post their whole life story on Facebook (subject)
// and people who don’t care (me) – joke…

And people who may want to keep updated on that subjects life changes(observer). The subject doesn’t really care (assuming it’s a public profile and they don’t check their followers) who is listening and people can easily hop in and read / be notified on the subjects status.

That’s how I understand it so far. To the next video!
