Annotated Dear Bob, by Jeff Jarvis (BuzzMachine) I learned long ago in my career that shorter is harder. When I started Entertainment Weekly, I decreed that long reviews usually waste readers' time with critics showing off. Shorter can be smarter. One doesn't measure comprehensiveness with a clock or a ruler. Longer is not deeper. ❧ I was particularly struck by two quotes in the comments which are very similar to a popular saying by Blaise Pascal. Are these truisms proven out on a daily basis by Twitter?
