Hi,
Please take a look at this video http://videoarch1.s-inf.de/FP.2005-SS-Giesl.(COt).HD_Videoaufzeichnung/2005-SS-FP.U09.2005-07-06.HDV.avi
Here Monad's are explained as "something" that helps making your program modular. The teacher gives an example implementation of an expression evaluator with and without monads. It takes a complete rewrite to incorporate changes in the program without monads where as only minor tweaks are required for the implementation with monads - also, its easier to identify the location where change needs to be done and the change is isolated.
And the flow is pretty nice - as in, people will not doze off :)
Regards,
Kashyap

Too late! The audience has already dozed off.
