This is great news. I, for one, am glad that Steemit hasn't gone completely mainstream yet, considering the UI could still use a facelift. However, I think that once more of the world get's accustomed to cryptocurrencies and the blockchain, Steemit could be huge.
I wonder if someone will start an app on the Steem network that is more similar to Facebook one day. I imagine that would do very well, considering Steemit is more similar to Reddit.
