At some point, everyone was talking about it, I've even seen people in the introduction section writing how they quit their full-time jobs, etc... just to stay with Steem and now, It's pretty much gone with ~100m $ market cap while It was almost 300m $
They got some thousands $ from their introduction posts,( pretty girls mostly) and believed their income will continued like that. I haven't visited steemit recently but the last time i checked some bloggers made significant amount of $ on every post. (because they were upvoted by whales).
