Make them laugh or not
I think the old cartoon format is perfect for digital media, especially when it comes to smartphones. Can you make people laugh by catching their attention for a split second, then you have succeeded.

Sometimes it feels as if you are a comedian testing your jokes on an audience, to see how many people think it is funny. It is also interesting to look at the data to see what age groups and gender think your material is funny.
