Key Takeaways:
-Bing uses data from Google in their algorithm, Google denies using Bing data.
-Both Google and Bing are using user data in their algorithm
-Google is coming out with a chrome add on that will allow user to veto sites from their search results (goodbye e-how)

Nothing major, it appears all three engines are still trying to figure out how to dismiss low quality content from their search results. Blecko is just flat out banning sites, such as Demand Media.

Bing did say that "author authority" may become more of a factor. For instance, if you continually write content that gets shared often, your personal authority will grow and so will the rankings of the content you produce.

Again, the best long term strategy is always to produce quality content and create trust/authority. But until they figure out away to stop ranking low quality content, spam away! Just don't be surprised if one morning you wake up and your site is banned from the index.
