I think the biggest disconnect I see with this is that few people use Twitter as a <i>synchronous</i> one-to-one communication tool. It's used as an <i>asynchronous</i> one-to-one communication tool, and as a <i>synchronous</i> one-to-many / many-to-one communication tool. But the Jajah offering seems to be forcing a technology into a paradigm that isn't built for it.
A <i>2-minute</i> phone call? I'm supposed to interrupt my workflow for the sake of a 2 minute phone call?<p>No. The only time I want to get on the phone with someone is if I can communicate faster or better that way.
