Right! I was definitely thinking about having user-submitted prompts. I think it would make sense to allow certain prompts to be marked as 'for someone' and then optionally be notified about them if someone actually fills it.

There's so many interesting possibilities here! I think I want to build something extremely simple at first and then start building features on top of it. But I need to really drill down on to what the core of prompting/fulfilling is before I can start doing that.
