I don't usually use NULL values for anything because no matter how much I read I can't figure out the purpose of it. So far this hasn't been a problem for me, but I figure it's going to trip me up sooner or later.
I've read the NULL sections of the PHP & MySQL manuals and even tried googling for articles, but the concept of a “a missing unknown value” makes my brain hurt. Can someone please, please, please attempt to explain--in the simplest terms possible--what the practical advantages/disadvantages of using it might be?
