Ask HN: Idea Sunday

It's that time again everyone. Last week this thread was pretty successful, as we saw a great discussion taking place among a huge variety of different ideas. So refresher if you didn't see it last time, post any ideas you're juggling in your head for product ideas, businesses, or general problems you have in your life.

Together we can strengthen our ideas by exposing them to others and introducing them to the world.

Go!
