Facebook-like Feed?

I’ve noticed that people at discourse seem to take almost a moral stance against social network-like features, and I’ve been reading and researching to try to understand this better.

What’s wrong with just sharing something that you want others to celebrate and react to? Why would discourse not consider supporting such a functionality like an activity feed? The endless scroll activity feed is what leads to so much success with Facebook, LinkedIn, Instagram, etc.

I guess the idea is that discourse is meant for serious discussions and answering difficult questions, and not for celebrating accomplishments. For instance, in my company’s Facebook group, the most popular post is people passing their exam and sharing the photo.
