"It indicates that blogging continues to play a critical role in debates about the important issues of our time" said David Sifry, the founder of Technorati.
Technorati is now tracking more than 57 million blogs, of which it believes around 55% are 'active' - updated at least every three months.
While the daily figure of 100,000 new weblogs is down on the 160,000 total from June 2006 it does not indicate a slowdown in growth rates.
It just means that more spamblogs or splogs - fake blogs used for promotion of affiliated websites - are being filtered out of the index.
Technorati ranks blogs depending on how many sites link to it. The blogging elite - weblogs which have more than 500 other blogs linking to them - number about 4,000.
Many of these blogs have been in existence for several years and tend to have new posts at least twice a day.
"Some of these are fully-fledged professional enterprises that post many, many times per day and behave increasingly like our friends in the mainstream media. The impact of these bloggers on our cultures and democracies is increasingly dramatic," said Mr Sifry.
English and Japanese remain the two most popular languages in the blogosphere. Despite problems for bloggers in China, Chinese remains at number three.
