I'm getting close to a year on Steemit now, and for the most part I get about 3/4 of my rewards from my comments. I don't bother to track curation rewards, as they're too little to consider.
Mostly though, I don't care at all about rewards (my personal rewards. I care about how rewards impact society). If all you care about is your rewards, do go away.
Don't come back either.
If you actually care about things that matter, then I hope you are well rewarded for your contributions here, and stick around, regardless of the money you get, or don't.
If all you want is money, go mine cryptocurrency somewhere else. If all you want is popularity, learn to twerk. If you want to engage with people and discuss fascinating ideas and society, then welcome to Steemit!
