I like to use 'I Can't Believe it's Not Butter' on my toast in the morning, because sometimes when I eat breakfast, I like to be incredulous. How was breakfast? Unbelievable.
The shortest feedback loop I can think of is doing improvisation in front of an audience.
I think it would be cool if you were writing a ransom note on your computer, if the paper clip popped up and said, 'Looks like you're writing a ransom note. Need help? You should use more forceful language, you'll get more money.'
Whenever I'm on my computer, I don't type 'lol'. I type 'lqtm' - laugh quietly to myself. It's more honest.
