A point.
You have a point, here. I've also heard the, "You didn't make a flash, so shut up," bit. I happen to be a Graphic Design student who spends more time on homework and a job than I do on animation.
Anyway... You're right - People don't HAVE to make a flash movie to know what looks good in one. A director of a film probably can't act worth crap, right? But he still knows what looks good, what doesn't, and what'll please the masses even if it isn't perfect.
In regards to this clip, I think you could have at least added a 'play' and 'replay' button onto the ends to make it a little more professional. Also, if you had a mic, you might have also read your text aloud and/or added footage of yourself ranting to make it a little more humorous or something.
