I just finished a similar experiment. After posting several times a week for a month - and doing a fair amount of curating - the liquid portion of my earnings amounted to about USD300 at today's SBD rates. Given another six months of working with this platform (and assuming the price of steem does not irreparably collapse) I suspect my liquid earnings here will be about equal with what I am accustomed to making from other online writing gigs.
So as a primary income, steemit at present doesn't cut it for me. But as a long-term investment and profitable hobby, it is proving to be very impressive. Hope your efforts prove as fruitful!
