If you have daily stand-ups, why would you have 30 minutes worth of update per person?

This whole article is pretty extreme. Standups, just like any other process (light-weight or otherwise) is only good until its original intention is being served. If a standup is taking a long time, make it a point to cut it short. If someone is narrating a long story, ask that person to stop and take the rest offline.

Finally, everyone should understand that stand-ups are used to convey status and information about important things. It's not a recital of what each person did the previous day. Sometimes, you might have nothing to say and in that case, just say so. Nobody should be talking about details in standup.
