Yesterday a friend mentioned that a favorite band was playing in Colorado and that someone in the audience with a pair of microphones would be streaming the show live
via the internet. I went to the link (what's there now is a recording, not live) and sure enough could hear the audience and the music being sent out to the world. It sounded great (especially on headphones) and it was cool to be "sharing the moment" all the way over here, in Japan.
Also to the right was a screen that looked exactly like live chat, with over a hundred people participating via twitter. Some were in the audience, some were sitting at home texting on their cell phones or computers, all listening to and commenting on the music, as it was being played.
Definitely meaningless, lol. Listening and reading simultaneously- it was multisensory junk food for folks with ADD.. but anyway, the point being that there are similarities with live chat... when people's messages are clustered together.
Do you ever do live chat, or instant messaging? For me, it seems to have some of the same limitations (and attractions) as twitter...
It's fun, but probably not very healthy.
