I'm a bit worried now reading this post, since I want to run a webseries[1] on YouTube too this year. Is there anything I can do to prevent this from happening to me? YouTube would be the easiest way to get it out there, being its own source of traffic in its own right. However, would Vimeo be a better option here? Obviously I could also run it from the website directly (e.g., cloudfront), but free services are always good too... :-)
Why just use one? Upload to YouTube for the traffic, and blip.tv or Vimeo for the reliability. And whichever you do, try to get as many people as possible visiting your site directly and not caring about the video host.
