Twitter ye not?

As Twitter makes more inroads into my professional and social networks I've become interested in two different phenomena. The first is about the silences, particularly those periods in the day when those I'm following go quiet. What has distracted them? What is it that they are not tweeting? The second is in part provoked by Rebekkah's idea of the "refuseniks". Those who don't want to. A colleague spoke about this today, referring to it as the invasion of trivia. I don't want to know. What's interesting is that I do! And what informs those choices. Whether you Twitter or not, my own Twitter Fountain should display above (I hope!).
