That DLive update is truly awesome. The description of how this can pull people in who don't necessarily have a steemit account or know a lot about crypto seems like a compelling use of the new functionality. It does make me wonder if the SBD peg might be a really important component of that puzzle.
As I understand it, the original design intent of SBD was to have something that is an easily tradeable and stable currency. It seems like it would be easy enough to create a system where people could create an account and fund it to pay out rewards with SBD (charge credit card $5, get $5 SBD). The problem with trying to do that, currently, is that you would have to explain that for $1 you would get something like $0.33 cents SBD and that the value might fluctuate wildly depending on market speculation and such.
I know there are reasons why having a high SBD value is beneficial to the platform generally, but it does seem to be problematic for this use case, which I think gets pretty close to the original intent of SBD. Maybe the platform can start issuing a separate meta SBD Dollar (SBDD), which is really pegged to USD? That's intended to be a joke, sorta.
