A rating on an article that arrived only via an aggregator (HN, Lobsters, Reddit, Scour) used to count fully against that aggregator feed. Now the aggregator feed gets a quarter of the credit and the article's author gets the full credit, so future articles by the same author from any feed carry the history. The feed signal is the mean over rated direct feeds and the rated author.
