And that’s how I feel about links in general: the source author creates something worth linking to, and the rest of us can link as we see fit, regardless of how we found it.
The proper place for ethics and codes is in ensuring that a reasonable number of people go to the source instead of just reading your rehash.
Codifying “via” links with confusing symbols is solving the wrong problem.
[True true. Which is why I try to rarely quote so much of an article that you’re not interested in reading the original.]
