If you are an avid Google Reader user (like me) you must be surely be “sharing” items that you read, for you or for your audience; in my case, you can see my recent “shared items” in the sidebar at the right side of this screen.

But can you export these shared items to a file? Google Reader does not allow you to do that from the interface, but you can use the URL below to do that. Just replace {USER_ID_HERE} by the ID of your user ID (it might require your Google authentication), and you’ll get the last 10’000 items that you shared in the form of a long Atom XML file, that you can download and store.

Update, 2009-11-06: The URL has changed (thanks to Jordan Peacock for the heads-up!); try this URL instead now:

[source:php] http://www.google.com/reader/public/atom/user%2F{USER_ID_HERE}%2Fstate%2Fcom.google%2Fbroadcast?r=n&n=100000 [/source]

Update, 2009-11-06: Check out this project on Github, which has a set of scripts to help you download your shared items to HTML pages in your own computer for later reference.
