David, its most interesting to read your blog. But as you demonstrate most clearly, twittering is a good tool for short messages only. It is not a tool for analysis or developing anything close to a complex idea.(Unlike blogging).
While democratization of the media is undoubtedly a phenomenon of our times, I am not quite sure that twittering small packets of information will make a huge difference in this regard. Too much information (without analysis) can be as painful as too little information. How does Haruki Murakami put it? Just shovelling cultural snow?
Anyway, please do twitter your next blog, I look forward to reading it….
