> I feel confident that Facebook has stumbled on something in our animal behavior that draws us closer to it.

I strongly agree.

I also believe that it is very easy to disturb their black magic.

Ever since I started using Stylish to customize the interface, I find myself less compulsively drawn to it. My version of Facebook remplaces all the blue for red hues and adds a wallpaper. I find that this makes Facebook more tiring to use.

This must be why Facebook is so against browser apps that change their features even when it's only minimally.
