Just like anything else, I've seen them done well, but also badly. My current stand-ups last probably 10 mins (never more than 15 mins). It generates questions and discussions that are carried out after the stand-up with a more focused group. If you aim for "transparency" in your process and company culture, I think stand-ups are not intimidating and are not waste of time.
