much a twitter about nothing?

I am getting increasingly interested in participating in twitter, friend feed and perhaps other forms of social networking. This Week in technology podcasts feature many lively conversation on these emerging media. The relative merits, conflicts and potential interaction between these different but potentially harmonious platforms is a simultaneously exciting and frustrating. It is fascinating that Lance Armstrong would decide to bypass official media and just send his statements out into Twitter. I would rather hear directly from Lance than through the mass media's filters. I find the whole concept of press conferences absurd. We don't need to assemble a rag tag collection of know it alls in one particular room to get statements anymore. In another twitter news http://mashable.com reports that rumours of an official twitter show are untrue. It actually is hard for me to imagine, but hey if more high profile people like the most successful cyclist of all time make it their main communication locus it might become a necessity.
