How many Blogs are out there ?

For the english blogs alone I got 9,736,407 when search for a common word like "the" and it only checks for the first occurance.

For the french I was suprise with 4,379,137 blogs for "la " with the space to do the french word only.

The most important thing is the speed with which the internet checked all these internet sites for the word.. a split second

Are we not looking at a big invisible world. How many request or messages are being send in a split second?
