That would make certain searches of news.ycombinator.com more frustrating.
Web pages that duplicate other web pages have been around for almost 20 years now (documentation by the GNU project being a notable early example) and even with all of their resources, Google still fails to filter out duplicates a significant fraction of the time.
Why do you think most people prefer to read it "inline"?
Far less snark, don't you think?
My answer would be: because some of my highest voted comments have been snippets copied from a larger work instead of just linking to the larger work. Perhaps people don't want to open up a new tab, perhaps they don't want to load a new page, perhaps they appreciate keeping the content in context with the rest of the comment thread, perhaps they appreciate keeping the content on HN for "prosperity sake" due to the ever-breaking links of the rest of the web.
Sigh. Thanks. This is the second time I've been caught with an eggcorn[0]. First "windshield factor"[1], now "for prosperity sake". Looks like I might have the privilege of adding to their database myself this time...
