I'm having the same experience right away. In particular I hate seeing lots of posts in the news feed that come from pages I don't like, but as some of my friend comment and like them they just appear in the feed. In these days here in Italy there's a very high level of stupid and uninformed discussions on politics, a lot of people post things that make me sick and they appear in my news feed (just take a look at this, to understand the level of discussion..

So I decided to stop checking FB very often
