I think one of the problem is when networks start mixing topics and people.

If it focuses on people, you can meet with real friends, and that's fine, because you get along.

If it focuses on topics, it is also fine, you meet people you don't know, but because you talk about subject you all enjoy, that's fine.

Problem starts when the two mix. If you enjoy astronomy for example, the other guy may be an asshole, but you probably don't even know and you get along fine, because all you do is talk astronomy. But if the network thinks that because you like the same thing, he must also be your friend, then your feed starts filling with assholish things.
