I wish I remember where, but I recently read something that argued most websites are still very basic in that they are using traditional revenue models. Few sites have innovative models that are unique to the internet. Linkedin is definitely in this category, but so are most businesses.<p>Selling ads while people reads your content? Sounds like a magazine. Selling a product? Sounds like a brick and mortar store. Even SaaS is really just a service you &quot;outsource&quot;.<p>Sites that take advantage of network size might be an exception to this though.
