This is nothing to d'oh about.

I've had this happen to me and I was thankful that we weren't going to have to wait 20 minutes. Now, don't get any idea to use this to increase customer satisfaction.
Here's my question for you, would you like updates every 10 minutes even if there is no new information? I know the captains I fly with have multiple schools of thought on this issue so on one flight you get constant updates and on another you get none.
I'd agree with the every 30 minutes status quo message.
