The article suggests that HTTP caching is "a fairly common practice nowadays." The claim is totally unsupported by any data and is likely incorrect. Most of HN probably have access to a web server on the Internet. Try throwing up some static content and refresh the page a few times. Notice any missing hits in the access logs? I doubt it. There would be no need for CDNs if it were cheaper for ISPs to build a massive caching proxy infrastructure than it is to just buy more bandwidth and routers. I don't see how that statement is any less true for bittorrent than it is for HTTP.
