I like this piece by Frank Chimero about how a function meant to encourage positivity (e.g. the Like button) ends up encourage active negativity, as there is no way to express disapproval except through negative comments.

I’m reminded how I changed my mind about Likes after joining Micro.blog. In the beginning, I assumed that Manton would be adding them, along with follower counts. But now I’m glad we have a platform that encourages positive personal engagement with a community of bloggers.
