dotnet.tv
I followed this dotnet.tv link via Ingo Rammer's blog. Lot's of fun with analogies and an enjoyable view. One of the comments asked for sub-titled versions of the earlier videos that were done in German. I'd definitely view them if sub-titled versions were available. Of course, English versions would be preferable - but just from the ability to bring up a video and be able to keep up with the story-line while doing something else at the computer that is more mundane. As the visuals are part of the primary content being delivered, this is only practical when doing other stuff that is mundane and doesn't take much of your brain power.
Carl Franklin indicated that he will be keeping .NET Rocks as audio only content - because "radio" is something you can listen to while doing something else. I tend to find that this works pretty well with some of the video interviews you get which are just talking head shots. It's good to see the people involved in the interview but then you can make the video window small and still have it running somewhere on the screen. The audio contains most of the content but you can flick your eyes back to the video occassionally to see facial expressions etc.
It's going to be really interesting to see how the media industry evolves over the next 5 years as more and more specialized media content becomes available. There's so much room for niche interests.
