If you've noticed your Home timeline here is pretty quiet it's because at the other place you were constantly hit with 'here's a tweet someone you follow has Liked', or 'here's another from someone you don't follow but someone you follow follows them!', or just general spam. So your timeline was constantly full of things you really didn't want to see and hardly any content you actually cared about.

In this place you only see posts from those you follow, so remember to boost the good stuff!
