ok this could be helpful to some
but I think true noobs could have a hard time following your explanations, because your visual support was kinda minimal,
some tips if you truely want this to work:
1. use visuals from flash (just hit printscreen on your keyboard and then import it into flash)
2. animate a mouse that will follow every step you explain
3. There was a little dot following a line which represented the progress of the audio, it would be handy if you could drag it around to skip to variouse points, to repeat certain parts perhaps.
I think with these ajustments you would have a very decent introduction to tweening that could be helpful to a lot of people.
