I really hope you guys bring the dynamic pricing back soon though. I know @beanz probably got lucky with that fill but at the same time, it's suppose to be an open market. With that fixed pricing, it's not a really good market for buying delegation either considering that you not only have to do a lot to break even, but worry about STEEM price potentially dropping as well.
In any case, you should probably consider dropping the APR a tad bit lower to attract more people to the service...but not too much that it causes an imbalance. +40% is considerably high even from my experimentation to break-even from buying delegation power.
