I guess we're pretty lax about it and not really following the rules. Almost always people do not respect the rules of the stand-up, and it becomes the status report meeting.

If you're doing it correctly, it should definitely not run over 15 minutes. Other groups that I've observed are having 30-minute standup meetings with 15 or 20 people and they're dominated by two or three people with lots to say.

That's not what it's for. I like your approach better than ours.
