Ask HN: Changing Video Online

I am considering taking a job at a video startup. I know many of you are saying yavs ( yet another video startup ), which sounds like a disease, but I really believe that video is a huge market and there will be room for more players.

so the question is, what are video companies doing right, and what are they doing wrong?

Ultimately youtube is turning into a Social VDN with some search, but Amazon, Netflix, Vimeo, and Hulu all have found niches' but is video being shared well?

How do you want to consume your video on apple tv, xbox, ps3, google tv, and maybe a roku?

If you have liked something like Dr. Horrible's sing along blog, when would you pull the trigger to pay for that video? Would you subscribe to something?
