To follow up a bit on my reply to your comment on one of the older posts:

1. Clearly this needs to get a lot bigger to make any real difference, with or without the DAO. There are a few million SBD that needs to get burned to fix the ratio (unless the STEEM price increases). With persistence perhaps that is possible but it won't happen overnight
2. The DAO is increasing the SBD supply, but not the debt ratio. 9x more STEEM is created per day as compared to SBD. This initiative should at least speed up the reduction in the ratio, even if the effect is small at first (see #1)
