[Air-L] Looking for academically valid stats about the internet

[Jeremy Depauw]

Hi all !!

I am currently trying to compile a set of data about internet usage and
especially about the following list:
-number of page indexed by google
-number blogs in technorati
-number à videos on youtube
-number of article in wikipedia
-nomber of user registered on facebook and on linkedin

Do you know if there is a central doc that woud provide those stat ? if yes,
is it, to your opinion, "academically usable"? Thank you in advance for your
help...

Jer'm
