Interesting article in Business Week; http://www.businessweek.com/magazine/content/10_03/b4163031536324.htm
My comment below;
"Top media sites often get $10 or $20 per thousand page views; even remnant inventory, leftover Web pages that get sold through ad networks, goes for 50¢ to $1 per thousand".
Lol - when you get back to reality let me know.
The current rates are closer to $5 and $0.25 pcm (unless you are counting pages that load up 10 ads to a page).
I think 3c per 1000 tweets is a little overpriced by about a factor of 10.
Randomly read some tweets and scan the 30 or so that appear per browser page, information that can be gleaned from that page is probably worth about that.
So what do you think? how much would the information you can glean from tweets be worth to you?
If you could slice and dice data to track interactions/mentions/user sentiment the way you wanted it - what commercial information could you gain?
