Twitter posted on it's blogerator today that they serve 50,000,000 tweets a day. That's 600 tweets per second. Now, I'm not a huge fan of twitter; I'm still standing way back, with my hands held up in that frame thing you can do with your thumbs are forefingers, squinting, trying to figure out what twitter's true value is. But I will say this, anything that happens 50,000,000 times a day is inherently important. If nothing else, that metric is a gigantic milestone in information velocity. If you subscribe to the principles of emergence, you'll get a hardon when you see numbers like these.
