If I understood you correctly you want to see every action of every one you follow so you can engage in mutual interests.
But you will unfollow them if they are active and have fun with silly comments, which floods your feed?

I see no viable solution here. Either you want to see everything, or you want to have a filtered version of everything or you go with the current solution to only see the stuff the autor explicitly choose to share.

I'm not unhappy with the current solution, but of course everyone is free to have another opinion :)
And as the blockchain is freely available it is a possibility that someday a more facebook like frontend enters the game, with the features you would like it to have :)

As for me I'm not looking at the comments of a person, so he can be silly all he likes, without me judging it^^ And I'm not sure how many do look at the comments and judges the person according to that.

And if I see a post and there are people laughing and having a good time under it I also don't see it as a problem, but just normal behaviour in a social network :)

So I don't really share your opinion about this plattform.
