How to characterize the Web? (see here)

WWW servers: about one million 
Institutions are less than servers. How much?
Typical HTML page: not standard, a few Kbs, few images (layout) 
About 10 references, and no one points to it (or they are local pointers)
Top in-sites: main universities, Microsoft, Netscape, Yahoo! 

Top out-sites: Yahoo! 

WWW size: at least 600Gb of text
