Dan Santow has a good point, which is to narrow down your two to three word phrases to one word. On Twitter, you only have 140 characters to say what you want. A lot of writers tend to add words to embellish their writing which, in the wrong context, can actually be a distraction from the topic. Twitter forces you to reconsider how you phrase what you want to say. It also requires more thought about including only the information that is necessary to make your point.
