Post-It Love should make all the filmmakers out there want to pick up their cameras and start shooting. If I was teaching a class, I would make it a requirement to produce a short with no dialogue. Tell a story without a single spoken word. Film is a visual medium and films are often at their best when the images on the screen do the storytelling. It is an incredibly valuable discipline to learn.
If you aren't familiar with Charlie Chaplin's films, go find City Lights and watch the ingenious methods Chaplin devised to tell his story. Too often, dialogue and exposition are crutches for a filmmaker. If you're a hobbyist like us, pop in a Blu Ray and try to spot moments where dialogue could have been replaced by a visual.
And if you don't like that advice from some blogging chump, then go to a petting zoo and find an ostrich. Steal the ostrich and ride it across the country, only stopping every so often to plant watermelons. Maybe someday everyone will call you Freddy Watermelonseed.
