It is hard to keep things running when you're changing and experimenting. It's why Google shutters businesses it finds are not growing - they're a maintenance burden and suck up resources, dragging down other efforts. And that's for a company with near-infinite resources.

Someone has to care and devote time and attention to keep it there. At the expense of other opportunities.
