Do you hear a ringing sound? As I suggested earlier, the iPhone launch is going to be a case study vehicle for social media anlaysts. Hey presto - BuzzMetrics put out a press release and will follow up with a web cast. In addition, they will be offering a syndicated report.

My prediction is that chatter in the blogosphere about the iPhone will hit 1% tomorrow.
