Well, that is dependent on how Mark Zuckerberg and the Facebook team will implement their solution. Zuckerberg tweeted about being investigating how Blockchain and cryptocurrency can assist Facebook to go to the next level of business recently.

In my opinion, it is all about user adoption. One of the key challenges for any cryptocurrency is to get their tokens, into the hands of the masses and after that give their ways to spend these tokens. Steemit is currently doing an excellent job in getting more and more non-crypto people into the crypto shere. Smart Media Tokens will take this one step further in allowing any website, to create their own token and incentivise users to use their applications and websites. I have been researching blockchains and crypto for a few years now and believe that there is no better solution out there than SMT's for social media based sites.
I do however also believe that a large entity like facebook will plan very carefully in which solution they will choose or for that matter maybe build their own solution as they have a captured audience and it doesn't really matter what solution they implement it should be adopted fairly easily.
In my opinion the reason that Zuckerberg is looking into these types of solutions are that his competition is getting a bit more everyday. If we look at a site like 101 Image is becoming very clear that more and more competition sites will pop up. Sure the business model for these types of sites still sucks, but this will become better over time as well.

The world of crypto will influence many industries, including social media sites. It is a very exciting time to be alive if you are a follower of the latest technologies.
One thing is for sure, Facebook and the likes have a lot to learn from community driven sites like Steemit.
Steemit will always be a few steps ahead of the rest of the world when it is coming to incentivising users for social content.
