Use a widget to display publicly shared items on your blog or website. Give readers insight into what makes you tick, or just make sure that all your friends can see the funny video you shared even if they don't use Google Reader. Use the ready-made Google widget or others available online.
Other widgets are available all over the Internet that will display items from you Google Reader. There are some chicklets and buttons that simply link to your publicly shared website. Find more information about the publicly shared website. Sites like Readburner also offer widgets that display your shared items, but they’re also social sites. Widgetbox.com is a site where you can create your own widget, or use widgets that others have created. I like these two types for use with Google Reader Shared Items: http://www.widgetbox.com/widget/my-sweet-finds http://www.widgetbox.com/widget/moose-tracks-and-gonzodave. You can customize them any way you want to, but Widgetbox does require you sign up for a free account. If you are a Wordpress user, try this Wordpress Widget.
To add to a Google website, try using Google Gadgets. Go to Edit Page > Insert > More > Add a Gadget to Your Page. You can select from a myriad of gadgets, including some feed gadgets. At this time, this is apparently the only way to add your Google Reader feeds to a Google site.
