HBDpotato was a failed project because of the person running it. That's about all I have to say in regards to that.

@hbdstabilizer returns 100% of the money it receives from the DAO back to the DAO and even sends additional profit back to the DAO. Over time this is increasing the amount of HBD in the DAO available for other projects.

In my view, adding buy pressure to HIVE is a positive thing to use the DAO funds for. Higher HIVE prices means more money for stakeholders and a larger rewards pool to pay authors from.
