Changes more than once a day may be confusing.  The book is now identified by a 
date.  If there are different versions with the same date, it could cause a new 
user a problem.

Developers, on the other hand, build in their own sandbox and don't need the 
site to do it.

I'd recommend leaving things as they are and render once or at most twice a day.
