Actually I disagree a little. I think it may be the death of facebook yes. And if the mobile platform goes live (on my iphone does not work), it could be the death of the instagram as well.
On facebook you have your friends. People post nonsense and things in their personal lives, and everyone enjoys it! Remembering that steemit in the future can undergo modifications! For example: implementing a chat between followers. (What happened in instagram). But even if you're right, we can kill: Twitter and Instagram also beyond reddit.
I think it still misses to steemit a little more publicity, but things are moving! I'm still learning ! I would like to know a way to track the number of registered users on the network. Can you answer me where I go with that?
If Steemit changes to become more like Facebook, then it has a better chance of killing it. Right now it's closer to Reddit than Facebook in terms of features.
Not sure how to view those statistics in real time, but here is an official Steemit blog post on its growth recently: https://steemit.com/steemit/@steemitblog/state-of-steemit-big-changes-in-steemit-recently
