I hate statements like this ie 'best marketing minds alongside Ogilvy..'.
Who considers Seth equivalent of David Ogilvy or anything close? That's really quite ridiculous actually.
Oh yeah and Tim Ferris is certainly no Ogilvy either.
Ogilvy built a world renown career in advertising. Seth wrote books and started a small company that doesn't even exist anymore. He may have some good things to say but he is certainly not in the league of a David Ogilvy.
Lastly ideas and 'how I'd do it' don't matter as everyone knows. You can have tons of ideas a new idea everyday. Not even trying to implement the idea and just being interviewed about it is like hypothesizing how you'd pick someone up in a bar or win the Olympics.
