Marco’s post on this stupid “Curator’s Code” seems pretty definitive. I’d like to reiterate how I handle “via” links.
I have “linked” items where I direct the title straight to the source. In those posts, my goal is to get people to click through to those sites and read the articles, and not to stay on my site.
And I have “via” links at the bottom of some posts. These point to sites where I found the links I myself am linking to, if I didn’t find them through my own browsing. These links are meant to give credit where credit is due, but I’m not necessarily trying to direct my readers to them, since they aren’t the original content source.
So far, no one’s complained.
