What are the areas on the web that people are making the most money
without being a big corportation.

New York Times reports that scams like penile enlargement pills are
among the most profitable internet businesses to run at this time."

I would agree that scams are probably the biggest money makers for
those who do not fall into the category of a "large business".

You might guess that pornography would be one, but it isn't a
money-maker for most people. This article is from Wired Magazine is a
bit old (Dec 1997) but I doubt a lot has changed since then --

"Most commercial sex sites are amateur jobs that collect a penny or
two for each click on an ad banner but aren't set up to generate real
money. One sex-site operator estimates that only about 50 sites gross
$1,000 a day or more, of which only 20 or so take in upwards of $3,000
and fewer than a dozen earn more than $5,000. The big-bucks operations
are run by marketing professionals like Warshavsky, not college kids
or moonlighting computer engineers, and they make their money through
a combination of membership fees and sales of goods and services...."
