I just discovered your fantastic service a couple of days ago. I get your cost issue. I was about to learn and test basic queries from learning and reading former post related to steemsql. As a plankton, 10 SBD/month looks quite unaffordable for me. You could maybe later on consider subscription based on usage and max number of req/month (or even bundled with other kpi like rep, sp) etc so that little individuals with low consumption can still profit of this wonderful service. I understand that it will need some extra monitoring implementation from your side and that a first flat flee plan is the straight forward solution but i fear it will exclude the beginners and the weakest ones. I hope your short notice action will restore the necessary financial balance needed to keep your excellent service running.
