Back then Steem had superlinear rewards. Today, it's linear. It has been suggested that we go sublinear, which I think is a terribly bad idea because of sybils. If you want to take a look at how sublinear works, just look at the Drugwars economy, as already explained in my main account's blog post a week or two ago. I thought it was gonna get fixed since it's so obvious, and I didn't want to go into the same debate again and talk in circles like with Steem's econs.
