I imagine this will make their sentiment analysis better. Hopefully, it will be weighted sufficiently highly in the newsfeed algorithm that I can start to exert some control on the newsfeed again. I can mostly keep my feed relevant by blocking whole sites (huffpo, buzzfeed, etc), but it would be nice if Facebook knew when individual posts hit a &quot;breakout&quot; status and could appear in my feed again.<p>On the other hand, ion they use this too heavily, then the newsfeed becomes a serious echo chamber, where it is not only correlated to your friend group, but also to your &quot;optimal&quot; emotional reaction. Might be great for Facebook to sell more ads, but not necessarily great for the end user.
