There is definitely merit to the idea that Steemit becomes the "home base" for monetization of content on the internet, and then other social networks will feed into it - so if you are a Twitter celebrity (whatever that means lol), you would want to send people over to Steemit whenever you can.
That's a great example of centralized and decentralized platforms co-existing in a healthy eco-system. So yeah, I'm on board! That is an awesome view of how social media can develop for the next 5-10 years.
