Hmmm...depends who's definitions you use. If you use George Imirie's (http://pxbacher.home.comcast.net/~pxbacher/PinkPages/Alphabetical_Index.html
) , who coined the term, a bee-keeper is somebody who does things George's way, and a bee haver is everybody else. a master beekeeper, but highly opinionated (as we all know, opinionated being a rarity in the beekeeping world!! :-D ).
It varies widely. Some people like to have the bees, take care of them, but not a huge focus on harvest, not a lot of time to invest, but do well. Some are focused on more bees. Some on more honey. Some on pollination. Some commercial, sideliners, hobbyists. Somebody can not give a fig about bees but care for his beekeeping business perfectly and make lots of money. How one runs their bees will vary widely within those focuses.
But to put insulting labels on it is not so dignified, imho, don't get too caught up in beeing a "beekeeper" or a "beehaver". If you have a beehive, you are a beekeeper. If you intentionally neglect the hive and let the hive get taken over by disease and swarming, then you are not a good beekeeper. If you do everything just right and take care of them perfectly, then you can apply to become a "Master Beekeeper".
