I'm interested to see how it'll play out; I think it'll be a good thing overall because I've seen and participated in the obsessiveness of "what time of the day do I need to post to get the most likes? what caption will get me the most likes?" etc. that obvi isn't healthy. as the article mentions, instagram stories have been pretty successful despite the fact that no one other than you can see who's watched it, and there are no likes even associated with ig stories. so I think it should be fine
