I'd like to see SBD work better than it does. The upcoming hard fork has a couple of somewhat minor code improvements, additional code improvements can be made, and some improvements may come implicitly from scale should Steem (hopefully) grow larger.

I think it is pretty useful even without a perfect peg, assuming the peg is at least approximate. For small purchases a few percent fluctuation doesn't really matter. For large purchases people will adjust to the exact market price, but that's okay. Over time I think we can get there.
