back in 2008 I wrote a post [1] about the (then new) change between desktop app and a browser plugin-based experience. Honestly, I don't think they ever nailed the right mix of great content and flawless user experience.

Eventually all our TV-watching will be done online - it'll just by through a different service. Hulu seems to be well positioned, but only time will tell.
