No offense taken! I think you're broadly right that I could be doing a better job on reassuring messaging, and I'll put that on my work queue.
I also hope to solve any bus factor problems before leaving beta. Right now if I were struck down, I think I'd still have about 9 months worth of free AWS credits on the account running the service, plus any profits. (It's not quite a self sustaining business yet, but it's not that far from it either.)
