I have wondered in the past. Bloggers seem to have a dilemma when posting to their blogs. They don’t know if to make short, concise, quotable posts or long-winded diatribes. When people make both they usually make the former sound like forced witticisms and the latter like attempts at tuppence literature.
Usually most blog-ers master one of the two styles and dabble in the other from time to time. Me? I’m bad at both.
