The creator of “Technorati”:http://www.technorati.com/ apologises for some growing pains.
‘Right now, we’re adding 8,000-9,000 new weblogs every day, not counting the 1.2 Million weblogs we already are tracking. That means that on average, a brand new weblog is created every 11 seconds. We’re also seeing about 100,000 weblogs update every day as well, which means that on average, a weblog is updated every 0.86 seconds.’
Of course this is a self-selecting sample – those who know about and choose to register with the site – so actual numbers are even higher.
