Dave Sifry of Technorati has posted the first part of his quarterly update, which says that exponential growth continues. He says: "Technorati currently tracks 27.2 Million weblogs, and the blogosphere we track continues to double about every 5.5 months." (MySpace, Xanga and MSN Spaces all have more blogs than that, but no matter....)
"We track about 1.2 Million posts each day, which means that there are about 50,000 posts each hour. At that rate, it is literally impossible to read everything that is relevant to an issue or subject, and a new challenge has presented itself - how to make sense out of this monstrous conversation."
Spikes in posting correlate with real world events, as his graph shows....
