What I really can’t understand about producing and broadcasting videos on the internet is why some people try to replicate the standard television model. Ok: some video are simply great and worth the fadigue you need to watch them on your laptop. But the web is a different media. Period.
Here is a easy example I like from bigthink.com: short videos, just a camera and plain interview even to great personalities. What is interesting is often there’s a transcription of the interview. Plain but fascinating.
And talking about ideas, you already should know about TED talks. If not here you can find Alisa Miller talk on february 2008. What makes me like TED talks a bit more then others is the videos are relesed under Creative Commons Licence.
