Bill D, think of it as a keyhole. A tiny glimpse of a subject, but sometimes a few words are all it takes. I'm not talking about the folks who tell us they're going outside to feed the cats or go get a drink in the kitchen. Those who use it well usually have a sentence and a link, taking you to the rest of the story.

And if you decided on an affectation such as writing everything as haiku, 140 characters are sufficient for 17 syllables and three lines. :)
