I've noticed that too with my other accounts, curation rewards going down a bit. HSBIDAO is essentially curation payouts but they have a lot more HP as well as a sustainably set up system and I think that matters. I expect the earnings to fluctuate but for now it seems HSBIDAO is earning faster than traditional HSBI voting units. I expect an equilibrium at some point. In my opinion HSBIDAO is a great source of passive income for folks who don't post often. !PIZZA
