This is just a fun way to gain ideas (not an if spittoon, which (source by @pinkunz) is where you give off ideas at random) from other people.
You can use it to say like, “I can’t figure out what puzzle I could include in X room to get Y object.” And people respond with ideas.
I might use this myself, this is probably already existing, and you could use other features (for those who are frequent enough posters). But I don’t need it yet, I haven’t seen that other thread, and it also allows discarded ideas to be used by other people.
(Should this be in General Design Discussions ?)
