I think Russel Brand is intelligent, articulate and quick witted, while not a big fan of his stand up comedy some of his comedy interviews are the most legendary, entertaining and impressive I've ever seen.
On a personal level, while he seems to genuinely believe that he's very spiritually enlightened, I find his actions sometimes betray a desire for self-importance, intellectual superiority and popularity which restricts the impact he has in areas where he attempts to be a positive force for change.
I don't think a DAC would fit his ideology unless he thinks of it as a way to 'stick it to the man.' Hmm... Yeah he might be so pissed off with the establishment that currently controls everything that he may consider supporting an alternative. Almost any celeb endorsement/interest would be good publicity even if some of his views are the antithesis of what DACs are about.
