Please bring this functionality back. Every other social media platform automatically subscribes a user to updates on a post they have interacted with. To not have that expected behavior on this platform is not intuitive and hurts interactions because unless they somehow know that they need to manually click the follow button to get notified, the commenter doesn't get alerted when another user (usually the poster) comments in response. Conversations stall and users are thinking nobody is responding to them, when in fact, they are. We are ending up manually going in and @ mentioning the users which does notify them. But it's clunky and manual, when the rest of the universe does this automatically. Jacob Harris
