I’m not trying to write this much about Twitter. I’m really not. But Twitter‘s really trying it, and I feel it’s my professional responsibility to tug the reins to get it back on track. Specifically, it appears to be trying out emoji reactions to tweets — hmm, sound like anyone else you know?

The screenshots come from Jane Wong — seriously, Jane Wong is the best — and appear to show various emoji in the Twitter app interface as reactions to a tweet. Twitter‘s Director of Product Management, Suzanne Xie, confirmed in the replies that it’s something Twitter has tested as recently as last year.
