Mat Honan at recently experimented with liking everything on Facebook and had some interesting experiences for himself:

My News Feed took on an entirely new character in a surprisingly short amount of time. After checking in and liking a bunch of stuff over the course of an hour, there were no human beings in my feed anymore. It became about brands and messaging, rather than humans with messages.

And how quickly algorithm based feeds can turn into a serious echo chamber:

This is a problem much bigger than Facebook. It reminded me of what can go wrong in society, and why we now often talk at each other instead of to each other. We set up our political and social filter bubbles and they reinforce themselves—the things we read and watch have become hyper-niche and cater to our specific interests. We go down rabbit holes of special interests until we’re lost in the queen’s garden, cursing everyone above ground.

What was most interesting to me is how much his actions affected the feeds of his friends. His likes completely dominated many of their feeds, prompting ocmplaints and questions. So crazy.
