I wonder if I could be any good at Android development, because I'll be damned if there isn't still a need for a Google Calendar reminders workalike in Y2K19. (A mission-critical need for me, at any rate, and I suspect others who have a complex relationship with linear time.)
But like. It'd be so much more a thing I might actually do if I could get even $50/mo out of it. And I would open source it and I just don't know how well beg-ware gets compensated, even for cool fedi devs.
