I hadn't seen Dave Sifry's State of the Live Web from earlier in the month until now. Each time I am struck by the number of Japanese language blogs -- 37% of all blogs tracked by Technorati.

Quoted:
70 million weblogs
About 120,000 new weblogs each day, or...
1.4 new blogs every second
3000-7000 new splogs (fake, or spam blogs) created every day
Peak of 11,000 splogs per day last December
1.5 million posts per day, or...
17 posts per second
Growing from 35 to 75 million blogs took 320 days
22 blogs among the top 100 blogs among the top 100 sources linked to in Q4 2006 - up from 12 in the prior quarter

Japanese the #1 blogging language at 37%
English second at 33%
Chinese third at 8%
Italian fourth at 3%
Farsi a newcomer in the top 10 at 1%
English the most even in postings around-the-clock
