:If a customer is going to run their cable modem at 100%, it's much better economically to have them pounding on your news servers than on your external connections.
But I can see a lot of ISP's being in an awkward place on this one. It's one thing to have a customer viewing web pages of atrocious stuff. It's quite another to have documented policies of how many days you cache alt.binaries.pictures.erotica.pre-teen and dedicate support resources to it.
My provider, SpeakEasy, gets around that by simply providing a basic subscription to GigaNews. So, they don't have to dedicate support services or dodge the landmines of explaining retention policies.
