Steemit does claim that you can make [fractions of fractions of pennies] money by curating other authors' posts. In reality however, that is simply not the case for most members.

Steem-power does pay out about 8% APR, + if you setup automatic voting to instantly band-wagon onto the top earners like gooddream and nonameslefttouse and steemcleaners, then you can even boost that up a bit.

It's not bad for a hobby, but almost nobody is "making a living" at this. I mean, last time I checked, gooddream was making about $500 a month in payouts (which is hardly lambo cash).
