When I first started writing, I followed a lot of other people's rules like in order to be worthwhile, a piece must be at least one page (i.e. 350 words long). That's hogwash. After years of writing, I have learned that a good writer cuts and cuts and cuts again, until they can succinctly get their point across. What is important is to be articulate in writing. If Twitter teaches us one thing it is that you can often get your point across in 144 characters or less!
