Safari and the Cookies

Earlier we'd looked at Cookies.  Now after the upgrade to Safari 5.1 the Command + Comma command brings up a new look at Preferences > Security.  Go to Privacy on the bar there to bring up Block Cookies, Limit website access, and the list of Cookies and website data.  After carefully opting in to Cookies only to post to my blogs and then afterwards deleting all Cookies it was a shock to see a huge list of 595 websites which have latched on to tracking my data since upgrading to Safari this afternoon.  (To see the topic of Cookies go to Labels on the right side of this home page and scroll down.)
        Since starting this post I've had 35 new websites latch on to my computer.  Is this the way Safari is going to behave now?
