I think it would be a great idea too... think of how this could change recipes... lots of times I think we've all seen that it's just easier for somebody to SHOW another person how they make one thing or another rather than attemtping to write it out clearly, etc.
Besides just actually putting stuff on youtube... there's lots of interesting stuff on there people might like to link to (such as the infamous Ornish / Taubes / AHA debate)... and also lots of just funny stuff for kicks and lightheartedness and such.
I think it'd be lots of fun!
