OK, I want to know if there is any source that will list Web sites by
the amount of data they push (number of megs used in the requests and
data downloads, etc.).  For instance, I have been told that Kazaa is
the largest site - I am not sure, particularly since Hollywood has
been sending out the lawsuit notices.  I distinguish this from the
number of visitors to a particular site, or the amount of data housed
at a particular site (not interested in the deep Web database content
for instance.)   I am trying to ascertain that push the largest amount
of content out as measured by meg.  Any chance someone can figure this
out?  Thanks!

It might've been possible if all web content used a common interface,
but unfortunately too many use proprietary software. Off the top of my
head, top sources would have to include ICQ, MSN, AOL and Yahoo
messengers, the Yahoo and Hotmail email services, the Yahoo and MSN
homepages (because when folk log out of email they get taken there),
and the most popular search engines, Yahoo and Google.

Amazon would also be up there, because of the amount of data contained
in their pages, and because you can preview album tracks.

Also I'd include Geocities and Tripod, due to the sheer number of sites they host.

And chuck in any of the big pop-up ad companies.

Of all the above, I seriously doubt you'd find figures that cover the
amount of data they are sending out, although with Google you could
probably multiply the number of search requests by the average size of
a search results page.

Not only does Kazaa use proprietary software, it uses peer-to-peer
technology, which means that the data doesn't get pushed by Kazaa the
website at all. http://www.kazaa.com/us/help/glossary/p2p.htm

Ok, that makes sense, does it make a difference if I were to ask the
question in terms of sites ranked by bandwidth?
