Specifying Maximum Length of BLOB

Is there any reason to limit my blob sizes when defining a table? I refer to 
technical/performance limits, not the administrative limits of preventing 
people from inserting something that is "too big".
 
I can almost see a reason if I can keep the base row and the blob size below 
32K. Then the db _might_ be smart enough to keep the base row and the blob on 
the same database page. 
 
However, if I can't keep it below 32K then is there any reason not to specify 
Blob(2G) when creating my tables?
 
And anyone know if the DB is smart enough to store blobs in situ with the row 
if the total row is limited to 32K?
