Is linking to a printer friendly page as impolite as hot-linking to an image?
When you link directly to an image on someone else’s site, you use their content without exposing anyone to their advertising model or any navigation so that the person you sent there can explore the site. Printer-friendly pages, however, are a lot like direct image links in that there’s (usually) no advertising and there’s no navigation on the page.
So by sending someone to a printer-friendly page, you’re “using” their content without giving them any benefit. Is this true, or is my comparison flawed? And how long before sites start sniffing referrers on printer-friendly pages and disallowing those that didn’t come from the corresponding “normal” page?
