I adore SQL NULL.
The problem is that people don't use it correctly & the empty string can be a nightmare.
SOrry, not adding much to this, but it's a significant problem in the real world. People often don't understand NULL.

Numbers don't have this problem so much, it's really just strings and other types that can be "empty" without being null. Arrays, I guess, though they're not nearly as common.
