The contents of your newsfeed are mostly determined by the people you befriend and the pages you like, as modified by your mute settings. If your feed is full of garbage, try changing those parameters. Plenty of people have a good experience because they have given inputs that reflect what they really want to see. The same is true on many other sites, BTW, and across sites as well. If all of the content on SuperCoolTechNews was garbage, would you still visit or follow their RSS feed? Even Google creates a filter bubble based on what you've searched for and which results you've clicked on.

The internet is becoming ever more personalized. Whether that's a good thing or a bad thing for you largely depends on your own behavior.
