BIND 9.10 and later will keep popular domains in the cache by prefetching them if they are looked up shortly before they will expire. So trying to keep local copies of popular zones is less helpful than it used to be. (Unfortunately the prefetch option isn't mentioned in the HISTORY file so I had to dig through the CHANGES to remind myself when it was introduced!)
