This widget will display your latest shared stories. You can change the amount of stories to display and how to display them.
In order to get your shares, you need to know your user id according to Google Reader. This can be found by going to the ‘Shared Items’ link, and copying the 20 digit number at the end of your shared items link.
So something like: http://www.google.com/reader/shared/02774557510273097991 Where 02774557510273097991 would be my user id.
