Posting To Slashdot Digg And Minimizing Its Server Effect

One thing that will help with bandwidth if you submit a link to one of the larger sites (Digg, Slashdot, etc.) is to use CoralCDN. CoralCDN is essentially a caching/proxy service that will reduce the drain on your bandwidth. All you have to do to use it is append “.nyud:net:8090” (without the quotes) to any link you submit. All requests for that link will then be automatically routed through CoralCDN.
