Reading this entry means you proceed on your one risk. Do not spend your (or your company's) 'means of subsistence' on this figures!
According to the 21. W3B Study from Fittkau & Maass (the 'sample' is 100.460) we all need to correct our figures on the German Blogosphere. Fittkauu & Maass don’t tell about Blogs, but about Bloggers and it reads like this if you calculate one Blog per Blogger:
Per November 2005, in Germany there are at least
1.428.000 active Weblogs – with at least one entry per monthly
750.000 active Weblogs – with at least one entry per week
using the (N)ONLINER Atlas (June 2005) from the d21 Initiative as our base for the total number of Internet-Users
Here you find the W3B press release (PDF, German) and some more thoughts about this findings on a previous entry - sorry, also in German.
Will I change my number? No, but I will watch the noise about this findings and wait for comments and corrections!
