I don't think steemit will kill facebook, and I don't think it will reach the level of facebook popularity in the next 3-5 years. But not for the same reason as you!! I just think facebook is too big and will only get bigger.

When you're someone new in Facebook... how many likes will you get? how many people will see your new page between the +10,000 pages that talks about the same topic?!! the same is here for steemit...

The way to survive here isn't really making "good content". It's making "good friends" but unlike reddit where the community values Jokes and memes... in this community, they're considered low-effort posts and are frowned upon. "Good Content" is the best way to get friends here!!

The fast way to make friends here is commenting on other people, and writing good posts made with effort. when the people like your comment they will see your posts, if they liked your posts your name might get stuck in their brain.... when they see your name often with good comments/content... then they'll consider being your friends.

In social media the majority always wins, if you don't want to be in majority then create your own minority that is more "bonded" than them... But making this great minorty will take far more effort than joining the majority!!....

The worst use of steemit, is "write it and they will come"... this is a social media.. no one cares about someone they don't know!!
