Chatter is a wonderful way to see what the world is talking about!
Just enter your query, like "lady gaga", "#apple" or "@BarackObama" and watch as Chatter displays what the whole Twitter is saying about it - right now - one tweet at a time.
"Is this website down just for me?"
"How's the Lakers game?"
"What's going on in Egypt, right now?"
These questions are hard to Google, but it's incredibly easy to get an answer with Chatter!
You don't need a Twitter account to use Chatter.
You can change Chatter's looks to your liking: zoom in/out with a pinch gesture on your multi-touch trackpad, enter full screen with a key press, and change colors and backgrounds whenever you like.
Chatter is great for wall projecting at parties and conferences, or just to look at Twitter in a whole new way.
