My apologies.. I scanned back looking for the reference but couldn't

I agree with you in meaningful separating columns into tables as you
descibed it. I had just impression, that mysql have some inner

So Jay,
What benefit do we get if we only null columns in a separate table, since

count(*) will, because it counts rows
