I was about to bring this up.  When I was in college 15 years ago learning 
this there was conventional current flow which goes from + to -/ground.  And 
there was electron flow which goes from -/ground to +, because that is the 
directions that the electrons actually move from atom to atom.  But since 
schematic symbols were created with conventional flow type thinking (from + 
to -) that seems like the way you should think.  You don't want to start 
questioning what direction your diode and transistor symbols should be 
pointing if you are drawing a circuit.
