SBD is central to small businesses accepting to be a part in commercial applications on the steem blockchain.

Stability will increase with the number of users, the number and diversity of transactions on the blockchain, the number of communities.

Creating "enforced stability" like Tether or the Gemini dollar would of course be ideal but unfortunately is VERY expensive, above what steemit inc. could afford now.

SBD is the "poor man's (almost-but-not-quite-) stablecoin. Let's focus on bringing communities and increasing the number of users and the (non-spam) transactions on the blockchain and SBD will become less and less volatile, more and more useful
