Brad, the two code snippets are not the same. The second sends the :puts 
message to self. The class of self inherits (possibly over several 
steps) from Object, which includes the Kernel module. So normally the 
two code snippets have the same effect, but this doesn't have to be.

If you

a) are sure that the :puts method isn't implemented anywhere on the 
inheritance chain for your current self object, or

b) explicitly want to prevent eventually calling another :puts method,

then you can code in the explicit form. For me personally, I only would 
use it in the case of b). a) seems to be too limiting for my taste.
