I'm working on creating a new table in our database, and I'm wondering 
-- why bother with the possibility of NULL values in a field?  It seems 
like it always adds more work then its worth.

What's the benefit of adding the option of IS NULL when you usually have 
to check to see if its also blank (field = '' OR field IS NULL)?
