You can view Google's original post here. Here are some of the key highlights I noticed: A lot of talk about on-site variables being analyzed in this post, including keyword stuffing, low-quality content analysis, freshness indicators, etc. Also, another interesting topic is the fact that they regularly are discussing anchor text, in this regard fixing a bug that they had.
