Google (or others) will eventually be able to identify you as the author of a blog that you write anonymously, based on matching of your "writing signature", that you will have revealed in plenty to Google (or others) on services like Google Search, Google Talk, Gmail, Google Drive, etc. Anonymous blog posts or tweets will no longer be as anonymous.
