I was just interviewed by a journalist from Information who wanted to know more about ....weblogs. I always get these anxiety attacks when journalists probe me for facts and figures and historical facts and stuff, so here is some of the links I want to refer him to, and check out myself for the right numbers. Further suggestions welcome!
Rebecca Blogs Weblog History and Dave Winers account of how they came into being.

Laurel C. Clyde has 2 articles (this and this) with loads of links and facts etc on weblogs in a online journal called Freepint.

This article, "News By the People, For the People" by Paul Andrews at the Online Journalism Review estimates the number of worldwide blogs to be more than 500.000 (May 2002). Judging from the success of Blogger.com, I'd estimated there is more than a million worldwide, but of those several hundred thousands of them are most likely already "deceased". Blogdex only keeps track of 13359 blogs. You got any more recent numbers?
ISSN for weblogs
Armarium now has a list of approx 170 Danish weblogs (as of July 6th).
And the Henry Jenkins article on the weblogging phenomena in Technology Review.
