do you mean that Google is doing content attribution correctly since last year?

I'd say it's much improved - but still, it's wise to take every step you can to help Google out. Using rel="author" seems to help, especially when the author is building a good reputation. Sending a "fat ping" via pubSubHubbub helps. Delaying RSS feeds for a short while after publication also seems to be a good step.

And all over, guard your trust and authority like a hawk and don't let anyone associated with your site take questionable shortcuts trying to build links. Instead, always build links that can generate traffic on their own. Google will naturally value those links more highly for ranking purposes, too.
