This is what Sifry said in his announcement of the new Technorati beta:

The pace is staggering: we are tracking somewhere between 800,000 and 900,000 new posts made each day, over 40,000 new weblogs created every day. A year ago, we were growing by a gigabyte a day. Now, we’re growing by a half a terabyte a day. So half the battle is just keeping up with all this explosive growth, and I apologise in advance for when we stumble.”

Wow! What a numbers. I am trying to imagine how many people are having conversations via these weblogs a day. Massive context.
