When I talk to people about quitting Facebook, one of the things I hear is, "But I find out about cool stuff on Facebook all the time".
What I propose is that, by limiting the amount of things "suggested for you" by the Googlebots and Facebook targeting algorithms, you'll start to listen for and cultivate your own natural curiosity.
If you're able to quiet all of the media outlets that are constantly screaming at you and vying for your precious attention—and it is precious, don't forget that, ever—you'll be able to hear the little voice inside as it whispers to you, "pssst, what about this?".
When you trust that your own curiosity and inquisitiveness will lead you to things in a natural, organic way, you'll find that your level of investment into researching and reading about those things goes up, which only increases the odds that some real learning will happen, instead of the mere acquisition of information and data.
Curiosity also feeds creativity and innovation. If your brain is always full of how everyone else is doing something, how can you ever expect to discover how you might do it?
Dorothy Parker said "The cure for boredom is curiosity, there is no cure for curiosity."
If Ms. Parker had lived long enough to witness the rise of social media, she might have suggested that while Facebook and it's ilk may be the modern cure for boredom, it is certainly the death of curiosity.
