ClickZ has an article about blogosphere statistics.
I had seen some of it before at Technorati, but this information about blogger demographics was new to me. According to a Perseus study about 90 per cent of all bloggers are between 13 and 29. Which means that I am among the 7.5 per cent oldest bloggers out there. Ouch, maybe I can get a senior discount on my web hotel.
By the way, no bloggers over 69?
