~/.bashrc is run by all shells, including non-interactive ones.  This
can include shells that are started by shell scripts, shells being run
internally by numerous shell scripts within your system, etc.  The only
things you put in ~/.bashrc is "environment" changes (e.g., setting
variables, or other things like umask).  

~/.bash_profile on the other hand is only run by LOGIN shells, e.g.,
interactive ones.  It's okay to put things in here that echo to the
screen.  (Note that not all interactive shells are login shells; it
depends on how you start them.)

Hope this helps,
