By that kind of thinking web hosts, blog networks, message forums like this one, etc. would all be legally responsible for anything their customers/users put online.

Indeed your web host would have to pre-screen every change, no matter how small, you make to your web content before it could go online. The same would apply to your NOC if you have a remotely hosted server.

It could even be extended to ISPs, anyone that provides upload bandwidth.

The internet as we know it would could not exist. Not just big business. In fact it would be far far harder on the little guy. Startup, and monthly, costs on the web would be impossibly large. Ecommerce would be too expensive to compete with brick and mortar. All of the recent advances in communication and information exchange would be too expensive to use, let alone develop.
