Google search making use of Social Graph information???

Today, while I was searching for my name in Google, I saw that towards the end, it showed my Delicious bookmarks in the search results. There is definitely no occurrence of my name in the pages that were listed in the search results and the only connection I could see between ‘me’ and the search result is that I have bookmarked these links in Delicious.

Is Google making use of the Social Graph information that I provided while I was trying out Google Friendconnect? Doesn’t this raise privacy concerns?
