”In an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.”

Not only it consumes our capacity to think, but it takes time.
There are two ways this kind of thing gets into your life: it's either forced on you, or it tricks you.
But while some amount of bullshit is inevitably forced on you, the bullshit that sneaks into your life by tricking you is no one's fault but your own. - Life is short - Paul Graham
Managing your attention helps avoiding others tricking you and wasting your time.
