I don't think it's about waiting vs not waiting for episodes, it's about the fundamental structure of TV shows. Shows that release all at once are and should be created to be binge-watched (you can leave people hanging for multiple episodes on a topic without them being frustrated, things can not make sense for longer because it will resolve at the users watching pace, not your release schedule pace, etc), they're a different animal than shows being released weekly. I don't think one is better than the other, just different formats.
Mostly, Hulu will need to release content than can keep viewers engaged and prevent fall-off over time. A lot of viewers will power through poor pacing/acting/whatever when they can get to the "good stuff" later on as fast as they want, but drawing them back week after week will mean creating some compelling content, I would think.
