As Gillmor tells it in the introduction to his book, We the Media (available online), he and a couple other bloggers were live-blogging the event, commenting on Nacchio's speech. When Gillmor and another blogger started pointing out some discrepancies between what Nacchio was saying and what he had done, they noticed the audience started getting hostile. Turns out that a lot of them were following the blogs while listening to Nacchio's speech, and they didn't like what they were reading.
We could see something similar take place via microblogging during this Friday's presidential debate (or town hall session, if McCain pulls a no-show).
Current TV and Twitter are planning to run real-time twitter messages ("tweets") over Current TV's live broadcast of the debate. So instead of just listening, viewers can comment on what's being said and see what others are saying...in close to real time.
The Current TV website notes that it will broadcast "as many of your debate tweets as possible right over Obama & McCain, in real time, on our live broadcast."
If you want to take part, all you need is a Twitter account and an internet connection. Then just tweet to your heart's content...and add "#current" to your tweets so they'll be queued for broadcast. You can also follow these tweets by searching #current on Twitter search.
