It seems with the new sharing features built in to Google Reader, my practice of sharing ideas, thoughts, and fun stuff has shifted toward "sharing" rather than re-posting on the blog. The Shared items widget is visible on my blog page but it does not kick out a RSS post to alert you that there is something new.
Thanks to upgrades in Google, you can subscribe to my shared items when you visit my shared items page (http://www.google.com/reader/shared/jetaube) .
