It's much easier to make it look "gorgeous" when the timeline is full of gorgeous people, beautifully photographed.
Facebook seems to acknowledge this since now if you view a person's profile, it automatically scrolls past the cover photo so you don't even see most of it.
Oh and where are the ads?
Which no one would ever click.
Came here to say it won't look as pretty when you replace all those photos with random images taken by random people from their phones but the parent beat me to it.
