I’ve write a while ago about some bad exemples ou web interaction mainly when servers return errors or problems.
Today i’ve a example of a good interaction.
With a little humor you can put a smile on the face of the user, he can share the experience with friends and maybe you can get some new costumers. Or better, you just make the day of somebody happier.
This is a good experience. Now, think about your product, business or service and find some moment where you can surprise those you interact with and put a smile on their face.
