I don't think you should feel too bad. But there is room for improvement. Something that would be nice in Amethyst that Instagram used to do is to have a clear break in the feed that tells you when you're caught up. I think device notifications are inherently part of addictive design IMO. My amethyst notifs don't work so I'm actually happy about that. Maybe they should be off by default? (Opt in versus opt out). I also think content discovery is part of the addictiveness of social media. Remember Facebook pre news feed, did any of us give a shit about discovering new content?
