I got the impression that the OP referred to linking to useful information that already exists as a good thing, and reposting "common knowledge" when a link to the appropriate place or information on how to find it was more appropriate. In other words, the OP seems to suggest that teaching people to fish is good, and regurgitating data better linked-to or pointed-at is bad.

To put it elsewise, I think you misunderstood the OP entirely. You're answering something like "Why do people who just cut-and-paste some vaguely unuseful information based on keyword-matching get more upvotes than attempts to 'teach a man to fish' do?" with something like "Because you should teach people to fish." Huh? He basically suggested that very thing, and asked why more points go to those who don't take that attitude.

Granted, I think he probably could have phrased things slightly better, but not everyone in the world is as eloquent as I. Heh.
