The content of your article is interesting enough, in a (very!!) niche way, but you don't address the basic and fundamental issue with Twitter as a medium. It is obscure -- INCREDIBLY obscure --
compared to other media. When a tree falls on Twitter... nobody cares because nobody can hear it!!
Unfortunately, as technophiles and people who work in technology, we're too close to remember that
all the time, and because some of our circle of acquaintances use it, we forget that it doesn't scale. The vast majority of consumers do not care about Twitter -- they haven't heard of it and they
wouldn't be bothered if they had.
