I don't know, I've put about a 10th of the time into Steemit compared to FB, just because my friends are over there, and I'm pleasantly surprised. I think the barrier to Steemit thriving is the way the developers update the platform and keep the thing centralized. Not as fair as other crypto platforms for back-end. It's great for front-runner users like me, though!
T'is still early in the game. Thingd are constantly evolving - some barriers may get squashed while new ones pop up. Irregardless, it's a pretty cool space to engage in for the time being... :-)
Oh, I fucking love it! Cryptos look volatile, but the ones that last are going to make garbage money like USD freak out and show their true volatility.
