It's obviously created to cater to mobile users as most social media pages are these days, but that doesn't make it any less boring and bland.
I believe they changed it so kids with a cell phone as big as a tablet can use it. When facebook first started out it seemed like it was for PC users. It's not more boring or bland as you say, but harder to navigate your way around now. And it seems more like a "toy" website vs what it was before the change.
