Harvard Study Cuts Through Twitter Hype

This BBC article references a Harvard study on Twitter that shows most users never tweet. This is in spite of the explosive growth Twitter has seen over the last year.

I also like James Robertson's point about the parallel to the blogging hype of prior years.  There's definitely similarities between the hype of microblogging and the hype of blogging.

BUT, I think it's worth pointing out that most of the read/write web technologies suffer from the "more users read than write" phenomenon.  There have been studies (references anyone?) that have proved this.  So, I would say that Twitter and other microblogging tools are no different.
