Great initiativw, @timcliff! STEEM needs an independent community of developers!
One specific question: what's happening with all generated SBD? If we are continuous adding new SBD to the 14.5 millions, faster than STEEM (broken pegging to the USD), already we see that the debt ratio can go in only one direction...
Unless users convert, it just piles up. Nobody is converting when the price of SBD is above $1 USD.
The debt ratio is not necessarily only going to go up though. It depends on the STEEM price too.
