I have already asked this question on Twitter, but want to continue the conversation here since the character limit on Twitter is annoying: https://twitter.com/bcye_tw/status/1134284076544712704    My idea was to price it at $2/year, though this doesn't seem like a great idea to most others.    My reasoning was:     $2/year shouldnt be too much for anyone.   It would give me enough to grow, pay for operating expenses and maybe pay back to contributors.    The whole idea to make it paid was because a stunning ~0.005% donated when downloading Hello, Goodbye. (which is not sustainable in anyway).
