I think the problem with a how-to so in the vain of Twit.Tv is that we do not have the luxury of having the kind of infrastructure for a studio that kind of show would require. The round table and people taking things apart and demonstrating it as a group. Not only financially speaking the geography of where most of the content creators on the network are located is a major hurdle as well. I am only speaking as a sole content creator on the network, but those are some of the realities of it.
As far as the just talking heads part we do many different things with the network to not just be “talking heads”. For example during the Linux 30th Birthday celebration, we ended up donating $500 to the VLC. We have worked with FreeGeek to help bridge the digital divide so people have access to the necessary tools in today’s world. We have done things like the Job board for the community.
I can only speak for me, but I see the network as a whole looking to be a place to bring people together with varying approaches skill levels, and perspectives and having one common goal as it relates to Linux, OSS, etc. Which to me, that common goal is to use technology and OSS to leave the world just in a bit of a better place than we found it.
