Congratulations to Dalton and co for trying something hard and worthwhile, and wrapping it up responsibly when it didn't pan out.
It raises a lot of interesting questions about the sustainability of the "app economy" for me.
I continue to be at least somewhat optimistic that non ad-supported models are worth trying. It seems like Patreon is doing really well and is perhaps something we can all learn from.
We sort of took the tortoise approach to development, and this seems to have helped solve the chicken and egg problem with the userbase.
I will email you about it.
