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 "breakout" status and could appear in my feed again. 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 "optimal" emotional reaction. Might be great for Facebook to sell more ads, but not necessarily great for the end user.
