Thus their Newsfeed changes de-prioritizing articles, and thus (I figure) their experiments such as showing short posts in large font sizes, and enabling MySpace-like gradient backgrounds on text posts...
This dynamic makes me recall something: Anyone remember how back in the day (like 2006) Facebook had a feature called 'Wall-to-Wall' conversations? You would go to a friend's profile and just write a message, they would go to your 'wall' and reply, and mutual friends could see the conversation.
These days between the Newsfeed, comments on posts, and Messenger, the only reason I would post on another friend's profile is to wish them a happy birthday. That whole ethos of just having informal personal conversations with college friends on Facebook is gone.
