I agree with this. As much as we want to see Steemworld continue operating, seeing Steem stumble in price will cost a lot to support this. $50 ($25 after curation) will earn around 50+ steem per post, which means more than 1500 Steems to be sold per month to cover the costs. That'll be okay if the funding comes from SPS, which unfortunately is not deemed worthy of funding by the consensus of Steem stakeholders, or there are more projects worthy of funding than this.

I suggest pay-to-use feature, in which @arcange do in his Steem SQL. It has been successful and doesn't require funding anymore. I think the pay-to-use feature will be beneficial to all, the only ones who use will pay not the expense of the community or the reward pool.
