Ya' know... There aught'ta be "Golden Cow" awards for people that really, honestly, seriously do know frikking everything about the stuff they do - and are grounded enough to be enthusiastic about educating the rest of us.
If such awards did exist, Michael P (24p.com) and Bill Ferster (Stage Tools Moving Picture) would be my top two nominees.
A picture says 1000 words. Editors give them meaning.
I would have to nominate Aharon Rabinowitz (spelling). This guy shares so much of his time creating podcasts for After Effects.
I saw first hand the effect Aharon has on people when I worked the booth at NAB. A lot of people went out of their way to come over...when Aharon was there they all expressed their grattitude, most of them by telling him that they now can use After Effects because of Aharon.
