Having a Good Idea at a Conference?

There's room for having an idea and using that to drive your conference submission. Dan Abramov had a lot of it basically changed his life when he did this. He was just like here's a cool idea. I'd like to work on it. And those are also the easiest to deliver in my experience when you're talking about what you've done. It's like it's like a story rather than a monologue.
