Something I realized recently was that when I watch videos in any form (feature film, documentary, dramatic or comedy series, or short) I have this nagging feeling I'm wasting time. I think it's because watching is such a passive activity.

When I read, I don't get that feeling. Even here on HN where it is mostly wasting time.

I think this is why so much media has viewer comments. It's something to engage with and lose awareness of the passing time.
