I believe that the hot topic in search this year will be an increasing emphasis on AuthorRank rather than PageRank. This is win-win for the author and for Google in its attempts to root out spam web pages. I believe the Penguin/Panda updates will never achieve acceptable results by themselves.
Much has been written in a variety of places about how to verify your authorship of your web pages. You can also check which of your web pages has been verified as belonging to you as author by looking at the link for Author Stats under the Labs link in the left sidebar in Google Webmaster Tools.
The anomaly I have seen is that an article I wrote in 2005 before there was any way of verifying authorship is listed as a web page for which I am the verified author. Obviously Google is proactive in searching out authors and does not just wait for the authors to do all the work.
