If you're like me, you like to keep things organized. I mark all of my emails as 'read', even when I never actually read them...
The lounge emphasizes any new content every time you login. This makes it easy to see what you've missed since the last time you were active.
You can de-emphasize these posts by just reading them. Or if you'd rather skip one, just swipe left on it.
