Because a lot more communication is done over private platforms these days. When working from home even informal work conversations are done over some cloud-hosted chat.

I see dead posts.

The issue is that in real life you can talk one on one. With the internet you have go-betweens, moderators and all that which limit what you can say to each other more than the two parties themselves limit.

Of course the limited reach of the spoken word and inertia of the speaker put limits on how much shitposting you can do in meatspace, but sometimes it's still preferable to have as little moderation as possible and instead enable each user to filter outer the noise on their own.

I like the reddit and 4chan model. Content is clearly compartmentalized by topic with different rules for each subcommunity. Of course they are not totally free of moderation but it still allows a greater diversity of opinions with seemingly diametrically opposed groups existing side by side.

Many of the big social networks lack compartmentalization. On the other hand twitter demonstrates that it's not necessary, just helpful.
